Thunderbolt Products- Engine & Transmission Repair & Remanufacturing

This is where the dealerships take the engines to get them machined. This is a one stop shop. They can machine the engine take it out and fix anything that caused it to blow. They’ve been around for 100 years, Chris Sanchez was super knowledgeable and friendly, best price in town with the best warranty. They have the capacity and they are robust to handle almost all brands and engine types. The thing you must understand is that people need engines for a reason and a lot of times people just expect the engine replacement to cover everything and they don’t really understand how long block/short block replacement works. This place is the best and I am so fortunate to have found them.

These guys are awesome. Gave me a great price for my engine on my 2015 GMC Terrain. Did a great job on the installation. Got my car back running great. Went to other transmission shops beforehand and they tried scam into paying more than I should. Talked with these guys and they went into detail of what they were going to do, pricing, time frame...etc. Definitely gonna recommend them.

Took my 06 f150 in for an engine rebuild. Original estimate was for $4800.00. A month later I was told that it needed more parts that originally estimated and it would be another $3000. After reading the past reviews, I was apprehensive. But, agreed to the price. The day I picked up my truck, the check engine light was on, so I questioned it. I was told that it may just be sensors that needed to “break in”. Within 10 miles the light came back on and the engine started skipping. By this time I was 45 miles away. I stopped at an Autozone and had the code read. It was a misfire on cylinder 7. I called Jim who said that it might be a coil pack. I figured what the heck and replaced the coil pack. That didn’t fix it. Needless to say,, I was getting upset. Jim offered to check it out on the weekend. Willing to meet me by where I lived. However, we were both sick that weekend and just decided to take it back to their shop on a weekday. They spent 5 hours figuring out what was wrong. They told me that the fuel injector on cylinder 7 had an issue (NOT something that they were supposed to repair during the rebuild). I was a little reluctant to believe them so I took it to my longtime mechanic (who no longer did engine rebuilds). I have trusted this guy for decades with my vehicles. I got a call from him the next day saying that Thunderbolt was correct in their diagnosis and that it was repaired. He also added that he checked out the work completed by Thunderbolt. He was amazed at the level of professionalism and the exceptional work they had done. Unbelievable was the word he used to describe the quality. Right down to using dialectric paste on ALL my electrical connections. He was really impressed. Him saying that, really carried weight with me. I trust him. He had nothing to gain and was unbiased. So, thank you to Chris and Jim and the mechanics and technicians at Thunderbolt for the INCREDIBLE job and EXCELLENT customer service you provided!! You get what you pay for! You guys did an AWESOME job!!!!!

THUNDERBOLT did a fantastic job for me. Treated me like a customer should be treated and got my motor finished quickly. Motor is installed and running great with no issues. I highly recommend requesting RJ when Inquiring work. He did a awesome job for me.

My teenage son was not paying attention to the gages in his Mini Cooper and blew-up the motor due to a coolant leak. It is difficult to find anyone who will even work on those things. I checked with Thunderbolt and to my surprise, Skip the owner came out and personally took a look at it. He confirmed that that the situation was bad but assured me they could take care of it. They even sent a tow truck to pick it up. A few weeks later, it had a fresh motor build and it runs better than ever. They even upgraded some of the OEM plastic coolant parts to metal so the problem should not repeat itself. Overall great work and amazing service. On top of that, very reasonable pricing. Next time I have a transmission problem in one my cars which seems inevitable nowadays, I wont have to worry about where to take it.

Took my Mazdaspeed 3 there to get my engine replaced, engine was done and complete I give them that. The issues? A) Manual shift cable was caught on the engine, they denied it. Went to my other mechanic to have it fixed instead. B) Battery installation? Just look at the pictures and see for yourself. They placed a screw to make it fit. C) More adjustments had to be done by a more competent mechanic at another location at half the price. D) Over charged for a job that had to be redone and spent more money to fix it at another shop. Their prices don't match their quality and their customer service, very disappointed. Avoid this place at all costs. Update: I just want my money back

I had the misfortune of dealing with a representative of thunderbolt by the name of Chris my nephew works in a Chevy dealership as a mechanic he knows his stuff and had informed me in what was need for my truck this man started at 2,900 then continued with adding to the price to the point of saying it would come out to 4,440 that was not counting other charges for other things needed i went in to just buy a new transmission and have it put in that's all he made it a big deal he was very combative ill never go back there good luck to whoever has to deal with them especially that man Chris

I took my truck there during Covid, they rebuilt the engine. I was told that I had a 3yr/100,000 mile warranty because it’s a diesel. So naturally when I had an issue I took it back. They denied my warranty because according to them, the warranty started on date x, which was the date that I dropped it off for repair, not when I picked it up. I went to the BBB and complained and they replied that my engine was modified and that was why. But the only thing not stock, is my air filter. And my truck was broken into while they had it and they wouldn’t do anything for me at all. But since there storage area has razor fence, 6 ft tall, it had to be done by an employee. They took over 5k in tools and stereo. There owner responded to my BBB complaint with several outrageous lies, apparently he believes everything his guys say. I wouldn’t go there if there was no where else to go. Horrible experience.
