Car has a stock 4R70W in it with roughly 100k miles on it. It shifted fine ever since I have had it until I put the 2800 stall in it. It's still manageable and isn't undriveable by no means but I can't be sure whats going on internally lol! (Probably wearing it now) After the I put the stall in it sometimes wants to hold 2 gear and this seems to depend all on how much throttle you give it threw 2nd gear. Ive kinda thought that has something to do with it not being tuned and it wants to think your at wide open throttle. No biggy... The weirdest one Ive noticed is that large bumps make it jump out of gear lol. First time I noticed it I was going down the interstate with cruise set on 65, I hit a bump in the road and it jumps out of gear and held the cruise so it revved to 6k hahaha! Without cruise set it does the same thing. Any large bump and it just kicks out and you have to click it into neutral and back down to drive or something to get it to go back in gear. Thinking about doing the jmod upgrade anyway so who knows, it may change again. Also a tune needs to be done as well.</p></blockquote><p></p>
