i had the transmission of my Range Rover completely rebuilt by Eastern Transmission or at least…read morethey said it was completely rebuilt. I returned it twice within 4k on the tranny and each time they said the code was due to a wiring problem. I had the wiring verified ...no issues then the transmission opened not by Eastern and they found a defective solenoid. When they were told by the Garage that did the work, they denied liability. unfortunately I would advise to not go to Eastern Transmission.

I've been going to eastern transmission for many years. Recently they changed the way they do…read morethings and I believe they have different people actually doing the rebuilds. The owner and his sons are still the original people but the workers I think not. I had two differentials rebuilt within a few months of each other, one seized after 2 blocks of driving and the other diff they charged a ridiculous amount for 'special bearings' of which were not even the right bearings and caused the differential to fail after 400km. I found out what they had done wrong after having to send the piece to a specialist in the USA. The specialist took pictures and showed what they did, even to the untrained eye it was obvious they didn't even try to make any decent effort to make it work. That job should have been maximum 500$ according to the specialist, I ended up with a 4000$ bill. I would suggest never using these guys until the clean house.
