They kept me updated throughout the entire process and even sent me videos showing the work they were doing. Eddie explained everything step by step and never made me feel pressured. I waited a couple of days before leaving my review because I wanted to make sure the original repair was working properly, and I'm happy to say everything they repaired turned out great. I had a separate issue with the car that I chose not to repair at that time, but because I trusted their work, I'm now returning to have them take care of that issue as well. It's difficult to find honest mechanics you can trust, and I've had an awesome experience with them. Thank you, Eddie and your brother, for your excellent service!

It has been great so decide to get my 2002 Ford Explorer done here. The explorer was jerky only after a cold start so we tried going with a smaller fix before doing a full rebuild. I was quoted around $1k. It took around 5 days before I got my car back. He gave me a warranty of 2 weeks, full credit towards a rebuild, or after 2 weeks for 6 months, it would be $500 credit. The car was driving fine except during traffic so I had to bring it back in to get the full rebuild. It costed around $3k but I paid $2k since I got the $1k credited back. It has been a week, and the car has been fine since then. I recommend Leeco Transmission as they are very honest and kind. Sam was always friendly and does a good job. I believe they have employees here who speak mandarin or korean if needed. They do not have parking here, you just drive your car in.

A new BCM is very expensive and if I did all the work myself to source and replace the $800 BCM, both local dealers still wanted $400 to program my car keys and TPMS for the new BCM... and I would have to have my car towed to the dealer for the programming too. Luckily, I found Kar-Techs. I gave them a call and sent some pictures of the problem circuit board. Hector came that afternoon (Thursday) to pick up the board, said he could repair it, and returned Saturday with the repaired board. Since the board was repaired, it did not need to be reprogrammed for my car, and my car started right up. Hector said he found several components that needed to be replaced... he must be very skilled as these were very small components to solder in. Very impressive service... saved me a lot of money... and having to get my car towed to the dealer.

I had a very disappointing experience with California Transmission. I came in looking to swap Chevy Astro transmission and the high selling point with California transmission would be completed in a one day turnaround. However, unfortunately, I found myself having to call the shop multiple times for an update, and we're constantly hesitant to update me. In the end up having to wait three days to get my vehicle To make matters worse, they failed to properly reconnect my oil dipstick to the engine block, which is a basic but critical oversight. I know that mistakes are common, however, granted to the fact that Israel emphasize how professional they are 25 years of experience, I am surprised something like that went unnoticed so I went ahead and give them a call today and after the vulgar conversation, he gave me I decided that I ultimately had a write a review.
