I installed this kit myself. Ive never built an allison before and it went smooth. Instructions were good and Inglewood's support is the best you'll ever get. They reply fast, answer your questions, and are very knowledgeable. The transmission shifts perfect, couldn't wish for better with stock TCM tuning. I paired it with a Goerend R torque converter which these guys recommended to me. I love the way the transmission performs all the way around. No complaints whatsoever.

I ordered this kit for my 05 duramax. I installed myself and it runs amazing. Do not recommend u install unless you have good mechanic skills. The support from Inglewood is beyond top notch. Cant say enough good about them and their products. I put a Goerend R converter in which was recommended by these guys, dont have any regrets there either. There simply isnt words to say how good it is!
