Always does an excellent job . They rebuilt out dodge Dakota transmission and our Chevy Camaro transmission.

Dale was super kind , honest, and helpful. Can't recommend Hartnell Transmission enough! Will definitely return when/if needed and recommend family/friends. read more

Five stars all day!!! My situation started in July 2024 when my transmission went out on a road trip through Northern California. I was towed into Hartnell Transmission and met Dale. Unfortunately I needed a whole new transmission and had to leave the truck for a few days. Dale was extremely fair and honest, and did a fantastic job rebuilding my transmission. It even came with a 2-year warranty !! Fast forward to this week. The new transmission has been great but we experienced a minor issue. I gave Dale a call and he recommended two transmission shops in Reno where we could take the truck to be checked. The shop I chose stated the transmission was damaged beyond repair due to a clogged air filter and would not be covered under warranty. This made no sense!! I called Dale at Hartnell and relayed the message. Dale assured me that any issues with the new transmission would be covered. Dale called the other shop and ultimately paid for the diagnosis and asked that I take the truck out of that shop and take it to the other for a second opinion. Turns out there is no serious issue after all and the transmission was given a clean bill of health. I appreciate Dale's professionalism and excellent customer service. Now, I wish my transmission never died, but since it did, I'm very happy it ended up at Hartnell transmission. Thank you Dale!!!!! read more

When my automatic transmission went out on my Xterra at 310,000 miles the local mechanic sent it down to Hartnell for a rebuild. Everything was good for the first 2,000 miles then it just dumped all the fluid on the ground. The local mechanic had to go back and forth with them to get authorization to fix it under warranty and even then they just covered parts and not his time. It has been 60,000 miles now and it is leaking again, needless to say I will not be going back to Hartnell Transmission. I think I would have been better off going to the wrecking yard to get a used transmission. Over priced for the money spent and not a good value. If I could I would give a 1/2 star. read more

Called in the afternoon and Dale said he would be willing to take a look at our RV's transmission issues when we got there! To our delight he fit us in before closing, diagnosed our problem and got us back on the road the same day. He was honest and did not try to upsell us and serviced the whole system which included checking the fluid for moisture, dropping the pan, changing the filter and adding new fluid. They test drove it, of course also. Mark helped us too. Very fair price, especially for afternoon emergency. read more

Dale was so amazing taking care of my granddaughter's car while I live in another town. He was in communication with me thru the entire process. His customer service skills WOW'D me. read more

On 7-16-24 I had my transmission on my Yukon serviced. I am content with the process from A to Z. Thanks again.

I was recommended here by a friend and have had several good experiences with Aaron and this company. They stand behind their work. I have taken multiple vehicles here. Recently, in July 2021 my transmission went out on my ram 3500. I waited a couple weeks to get the work done but that's standard. Once they got to it they got it done quick. The price was normal compared to what I've paid other shops. Here's where they really earned their stars. I had an issue with it four weeks later and they took care of it right away. read more

These guys were so nice to me even when my 2016 Yukon literally died right in the middle of their driveway. I had my two young boys with me and they were more then helpful. They worked my rig in to get a new transmission installed within 2 weeks when they were already so booked out. Ended up having an exhaust leak after I picked it up, so I brought it back and they had it fixed within the day for me! Great service and very fair! I didn't feel price gouged. read more

I have brought several rigs here and they always get it fixed. Repaired with upgraded parts. They are the best shop around. Affordable, and I know they do a great job. I trust their work. read more

We had Hartnell replace the transmission in our 2008 Honda Ridgeline. They did a good job, including dealing with supply chain issues, very transparently. Then last week we were getting a warning light, whose code indicated a possible pressure switch problem. We made an appintment, drove the three hours to Redding, and dropped it off. They were crazy busy but they got the part and got it installed in less than 2 hours, under warranty, no charge. Great, courteous service. Thank you! read more

These guys are the best. Marc is a man of integrity and has been in business for a very long time. I find it comforting to work with men of honesty and to have a shop I can trust to keep me safe on the road. read more

Such a great experience. These guys worked on my truck for hours but only charged me what was needed or fixed. Main problem wasn't my transmission but they weren't about to sell me something I didn't need. Very honest! read more

My old school Duster was leaking fluid. I took it to this shop for a diagnostic and repair. Seeing as I work nights and my time is limited, they let me leave the car there overnight so I could get some sleep while they did their work. I picked the car up the next day and was told that it was not leaking transmission fluid, but it was leaking power steering fluid (which is similar in color) so no work needed to be done on the tranny. I then asked if they wanted extra money for the night they kept it, and I was told that "I only have to pay for the diagnostic". Some other shops would more than likely lie and say that it needed repairs just to get money. So between their honesty and their understanding of my sleep schedule, I must leave this 5 star review. If you have transmission issues, then this is the place to go!!! read more

I had a small problem with my rebuilt transmission from Hartnell. Even though it was past the 12,000 mile warranty, they took care of it. Its difficult to find a business that stands behind their word. Thank you Matt. read more

Great service and reliable work.They got my work truck back to me when they said and communicated and updated me the entire time.Very affordable and a great warranty.I would recommend if you are in need of any transmission repairs. read more

This shop is GREAT. I've used there repairs for years. Everything from a 76 monte Carlo transmission, 2001 transmission issues. And putting a hydraulic clutch set up in my 70 camaro. Mark, Matt and Arron are great and knowledgeable. The prices are resonable and the work is done quickly too. You won't be sorry if you get work done here read more

Hartnell Transmission - Transmission Repair Near Me - Redding, California

They were backed up but squeezed me in. Needed a new transmission and they were able to do it quick and at a reasonable price. Very professional and friendly.

I had a great experience here. They installed a TH350 transmission they rebuilt in my car after the old original weak transmission died. The job was finished quickly and the work was done well. read more

I tried out this shop on a strong recommendation by a friend in September. Four months and many miles after the repair on my 6 speed manual in a Tacoma and everything is perfect! The guys at Hartnell accommodated not only my schedule and fixed it up while I was out of town but also beat everyone else's price by quite a bit. That was a very pleasant surprise. Highly recommend you check in with them for any transmission repair. They will provide you with a straight no BS service. read more

These folks are great to do business with. They repaired my transmission in a timely fashion and were great communicators throughout the process. I was traveling from Washington State through Redding for Southern CA. I dropped my vehicle off and rented a car to keep on schedule. Upon my return, the vehicle was repaired when they said it would be for the amount they said it would be. I drove my vehicle 800 miles home and it runs great. They went above and beyond for my short schedule needs. If I live in Redding, I would patronize them exclusively. read more

Everytime I go into this shop for help I get nothing but the best customer service. Aaron provides quality care and is helpful in anyway he can with his customers. I won't be going anywhere else. read more

This place has great customer service! I had my transmission rebuilt from them, they offered a one year warranty on it. Well unfortunately 4 months after my warranty had ended, the planet gear broke due to a manufactures defect. Lucky, Hartnell kindly took care of the defected part and fix it without a cost. This is a loyal, good hearted company. Thank you immensely Hartnell. read more

What a pleasant surprise! The transmission in our 91 Chev PU went out in Sacramento on our way up to Seattle. We had it towed to Hartnell to get it closer to home. Finding a reliable shop is usually a crap shoot, but based on reviews we thought this transmission shop would be our best shot. We were extremely impressed with everyone at the shop. They had a new transmission in stock and got it in the truck and ready to go the next day...almost...seems we had an electrical problem that caused it to malfunction. So instead of sending us on our way just to break down by Oregon, they put the crew on it to get it fixed correctly. And all for the original quoted, and very reasonable, price! They really went all out to get us back on the road. I can't say enough about this shop. The truck ran great. It is home in Seattle running smoothly! read more

Had a car in there years ago. Trans-Am. They worked on it, but I did not receive a call. When I finally called them a couple of weeks in, I was told it needed rebuild. I told them we would come and get it. They then informed me that they had in the interim had it towed to a wrecking yard, as they figured it was abandoned. I was like you did WHAT? I haven't heard from you guys at HT since I brought it in, I end up having to call YOU, and then in the meantime you had it towed? I demanded they have it towed back to the shop where I would then have it removed myself from their yard. What a joke. That and they charge so much for services, that unless you are independently wealthy, you wont be able to afford them. Screw Hartnell Transmission and the old fart that used to run it. Nor-Cal Transmission all the way. Never done me wrong. read more

I had my 2001 Dodge 2500 transmission rebuilt by Hartnell Transmission. There was a mis- quote on the cost of the repair, but it was in my favor. They stood behind the quote. There have been a few small issues that have cropped up that have been transmission related since the rebuild. The thing that stands out is they have taken the truck, fixed the issue and without any hassle, no complaints and no new charges.They have been very easy to deal with all along the way. I understand why they have a great reputation! read more

i had my dodge 5 speed manual rebuilt and it made a howling noise when in reverse, i assumed this was normal cause it operated fine. 20,000 miles later it started making noise, even in nuetral. come to find out they never shimmed the main shaft and put the wrong idler shaft in.would not reccomend. read more
