The reason I have waited so long to post my review is I wanted to wait and see how things were after the 6 month warranty they give with their work expired. It has now been around 7 or 8 months since I purchased a motor and transmission from Kar King and they are running just fine. I would recommend this company to anybody that wants quality work without the inflated price tag. Before Kar King I was quoted $5900.00 from one shop (that was just for the motor w/warranty) and $3700.00 from another (used motor w/o warranty). Since these prices were way out of my price range, I decided to shop around and found Kar King. Not only did I get a new rebuilt motor (with a warranty) I also picked up a rebuilt transmission. I figured might as well do them both since the tranny had around 140,000 miles on it as well and had to be pulled out with the motor (easiest way to do it). The price for motor and trans was $2750.00!!!! Nobody else could even touch this price! Another nice thing about George and his crew is they stand behind their work. Long story short, there was a slight discrepancy concerning the transmission and it had to be sent back to Kar King. I called George and informed him of this. Kar King paid for all the shipping to and from their shop in California. Not only that but when they took another look at it he informed me of a different, more serious problem with my transmission. At this point he called me to let me know what was going on, that they had fixed it and was sending it back with a trans cooler.....FREE OF CHARGE! So to sum it up I think the guys at Kar King do a great job so don't bother looking anywhere else. A very satisfied customer

After 306,000 miles my Toyota Tacoma 3RZ FE lost Compression. I searched around and nobody came close to the Kar King Price. I spoke with George and he had a Long Block in stock. Replace a few other Item while I had the engine out. The machine work was incredible engine fired right up. Hoping for another 300,000 Miles. Great People! Tim Lenexa, KS

I bought an AX-15 transmission for a Jeep Wrangler. The product was shipped quickly and was exactly as described. I also called to ask some questions during installation and George was very knowledgeable. If anyone I know needs a new transmission for their Jeep I will definitely recommend Kar King Auto!

George was most helpful with the transmission we bought for a Geo Metro. He is friendly, prompt and very knowledgeable. Will be dealing with him again for an engine next time! Thank you Gentlemen it was a pleasure doing business with you!

Recently the transmission went out in my 1991 Geo Metro. This was the original transmission and lasted through 3 engine changes approx. 500,000+ mi. I drove the vehicle till it did not move and had to be towed home. In searching for a new transmission I found Kar KingAuto through their listing on eBay. The price $800.00 appeared to be an excellent price for a rebuilt transmission. After the order was placed and payment cleared, I received the transmission in about 3 days (Northern Ca.). I felt that this was fast shipping. The transmission was well packaged and protected for transit. I have installed the transmission and it works GREAT !!!!! Up shifting and down shifting is nice and smooth and the vehicle is quieter then I've ever heard it before. The vehicle runs like a new car. Thank you Kar King Auto. I would highly recommend this company if you are in the market for a rebuilt trans.

I took my smoking rattling 2010 Toyota Highlander with 69,000 miles to my local mechanic to see what the problem was. He diagnosed a complete engine rebuild ($7,000 total cost). It just didn't seem right. I did my research and found Kar King. I called George. We took the car in expecting to need a new engine, George did his tests and found that the car had several problems related to engine sludge) that all created the smoking. The total repair was $1,700. Obviously we are very happy.

I ordered a 2.2L engine for my 1999 S-10 pick-up. I installed the engine myself so I became very well acquainted with this engine. I did not have any issues with the install. The engine was painted and in great condition, ready to assemble. I took particular care, cleaning and painting the components as I installed them. Every tapped hole was clear and in perfect condition. The engine fired right up! I have a 1500 mile break-in period were I will check the fluids often. It runs and performs great. I am very please with this purchase.

Ordered a 4g63t for my dsm. Was delivered quick and motor is 550 miles strong so far. Only issue I have is the included gaskets and timing belt are horrible quality. I did not use those. But motor itself runs great.
