    Hard Downshifts Allison 1000

    It just sucks when a reputable shop tells me it’s absolutely a good idea to have trans tuning but then I come on here and see what all of you have to say about trans tuning. Makes me feel pretty dumb honestly but I guess sometimes you gotta learn the hard way. Just trying to learn anything I can...

    Because the transmission was 75% built when I ran into the first problem and the customer service got worse with the next 2 problems I had with their kit so it’s not like I had a bad experience with them before and decided to use them again. I guess I was too far along to decide to send...

    Super bad experience with them and their customer service to say the least. I’ve heard nothing but great things about Mike and his knowledge on Allison’s. Suncoast is the last place I’d call for help.

    Ok. Any reason why all of the sudden it’s starting to do that? I did a proper relearn when I tuned it and everything has been good for the last 6k miles. Just strange that all the sudden it’s acting up.

    Hard Downshifts Allison 1000

    I have a 2017 L5P and rebuilt the transmission with a stage 3 suncoast kit this summer. Haven’t had any issues for 6k miles and all of the sudden I’m getting hard downshifts from 4-3-2-1 and my 5-4 downshift has produced a howl. None of this is consistent though. Changed the spin on filter to...
