i don't know where these guys got that i have a stock tune...my rev limiter has been raised, shift points changed...my truck is fine...i was just curious bout something that it did but i have since figured it out

 

i have an 06 w/ 4l65e bone stock tranny. 2-3 shifts i have a screech/squeel AND if i dont manually upshift like 300 rpm before rev limit, it delays, hits the limiter then jams into gear. i dont have a tune either. its probably just the bands slipping or something. if its happening bone stock w/ 100% tq management, im not too worried about it. i have a tt3000, hd-2 shift kit with servos in the garage, just waiting for some money to get the nelson tune then im gonna install everything together.

 

well just keep us in suspense then why don't ya...

 

it was just bouncin off the rev limiter for a split second. only when manually shifted though...i'll just let the computer do the work
