Hard Thump From 4L60
I've got a beefed up 4l60E. Is it normal for the tranny to thump real hard when down shifting into 1st while coming to a stop? It's a pretty solid thump. Or is this a sign the tranny is going to take a dump?
Also, I've noticed that while city driving, my tranny will sometimes stay stuck in 2nd gear. I have to pull over and let it cool off for about 10 minutes so it'll work right again. BTW, I'm running a PT4000.

Yes it's tuned. Unfortunately I'm not sure what servos are in there. It'll thump going into 1st right before I come to a complete stop in "D".

I'll keep you posted as soon as my tuner hooks up the lappy!
