They spent 2 1/2 days trying to duplicate and isolate the problem, thoroughly checked the external wiring harness, and tested the suspected speed sensor. Everything checked out and the transmission continued to operate normally. Rather than guess or start replacing parts at my expense, they installed a used but known-good speed sensor they had available and told me to drive it and come back if the problem returns. At that point they can continue troubleshooting with at least two possible causes eliminated. Sometimes the best repair shop is the one willing to say, "We can't reproduce the problem, the transmission is functioning normally, and we don't want to charge you for work we can't justify." Five stars earned.

I am writing this review to warn future customers about my unacceptable experience with Affordable…read moreTransmission and Auto Repair Center regarding an ATRA nationwide warranty repair. Background and Initial Service: My vehicle's transmission was rebuilt a few months ago by a different authorized ATRA shop. Due to a recent move, the original shop authorized me to bring the car to this affiliate location, a 30-mile drive from my new home, for a warranty diagnosis. Upon drop-off on 11/18/2025, the front desk employee immediately became cold and dismissive when I mentioned the words "warranty repair." The Issue & The Refusal to Diagnose: The problem is specific and reproducible: when the car is cold, driving downhill causes the transmission to shift into what feels like neutral. Pressing the gas results in rising RPMs but no movement, forcing me to shut the engine off and restart it to re-engage the drive. After two days, I received a call informing me they could not reproduce the issue and were refusing to work on the car. I explained to Miguel that the condition requires a cold start and a specific downhill coast, asking them to try again or keep the car longer. He flatly refused any further testing, stating they were done with the vehicle. Integrity Violation and Fraudulent Documentation: Since they refused to honor the warranty, I requested a written reason for the denial of service, which is standard procedure. Miguel went to review my paperwork. When he returned, he presented a form and demanded I sign it before he would provide any written explanation. This form was an explicit waiver where I would acknowledge that the issue I claimed was not present and that their testing proved my claim was false. I refused to sign a document that was contrary to reality, as the transmission issue is demonstrably still present. The Threat and Escalation: Because I refused to sign the false waiver, Miguel refused to give me any written denial and escalated the situation. He told me he wouldn't help me anymore because I was "not a nice person." When I stated I would write an accurate review of this unprofessional experience, he raised his voice and began threatening me: Threats of litigation. Explicit threats of physical harm to myself and/or my property at my home. Threats to contact my employer to have me fired. I immediately took my keys and walked to my car, with Miguel following me out of the office, continuing to curse and issue threats. This behavior is far beyond poor customer service; it is menacing, unprofessional, and a direct failure to honor the ATRA warranty program. The shop refused to perform due diligence, attempted to force me to sign a false legal document, and threatened my physical safety. Avoid this business at all costs.

I can't say enough good things about Ed and his team at Transmission Specialist…read more My Ford F-150 suddenly went into limp mode and was stuck in third gear, along with a few other issues. Since my truck was out of warranty, I wasn't sure where to turn. I reached out through Yelp and heard back from Ed almost immediately. He had a good idea of what might be wrong and invited me to bring the truck in for an assessment. After inspecting it, he identified damage (caused by rats) to the transmission wiring harness, which had unfortunately caused internal damage. He walked me through everything clearly and provided a very reasonable estimate for a full rebuild. Throughout the entire process, Ed was easy to communicate with, always professional, and genuinely helpful with his advice. What really stood out was how he went above and beyond after the repair. I was told this type damage might be covered under my comprehensive auto insurance. Ed then took the time to work directly with my insurance company--providing detailed documentation and expert insight. Because of his effort and experience, the claim was approved and the repair ended up being fully covered. That level of service is rare these days. I truly appreciate Ed's honesty, professionalism, and follow-through. He did exactly what he said he would do and then some. I wouldn't hesitate to come back or recommend him to anyone in need of transmission work.

Last year, the transmission on my 2008 RAV4 was rebuilt by Transmission Specialists after tow truck…read moredamage, going through insurance. A year later it still hard-shifts going downhill. I brought it back twice and both times I was told everything was fine. During the rebuild, they replaced (and charged additionally me for) replacing the transmission mounts, but a few days after I picked up my car, my motor mounts broke and the engine shifted while I was at a red light. I brought it back immediately and, after a test drive, I was told everything was fine. A separate shop found the entire engine was tilted, and I paid out of pocket several hundred dollars for their diagnosis and installation of replacement motor mounts - mounts I was told should have been replaced along with the others. I brought it back several months later because my car was hard shifting whenever I went downhill and the alternator continued making a high pitched noise. After a test drive on the flat roads around Santa Ana with Ed, was told that it shifted like butter. He advised me to warm up the car before driving, which has not helped at all. I was also promised that my alternator would be exchanged for the price of parts from O'Reilly and that it would be about a $150. I was ultimately charged me $429 for the third party alternator (definitely not a Denso) that makes high pitched whirring sounds when I press the gas pedal. Other minor issues: scratched my window tint and took 6 weeks to complete the work, fixing the alternator last and costing me 3 extra days of rental fees my insurance wouldn't cover. I ended up paying $1345 out of pocket to their shop and insurance covered $4000. Also, I incurred an additional several hundred dollars to the other shop to fix the motor mounts and for the extra days of rental. Ed is really nice and communication was not an issue. Overall, though, I did not have a great experience and I'm reminded of that daily when I drive my car over the hill to get to work, as the car will inevitably jolt as it shifts gears going downhill. It doesn't leave me a good feeling that the transmission repair will last. For this reason, I can't recommend this shop for transmission or general repair work.
