07 nnbs transmission issue

[chadt256]

ok so on my 07 sierra with 60,000 miles on it the tranny obvisouly went out.. i stopped at a red light and when i went to take off there was a slip then a loud clunk and it went.. ok so at the next light i stopped again thinking it was nothing, well when i took of this time another clunk then there was no drive or 3 and barely 2 and had park reverse and 1... so its at the dealership under warranty, but what the hell? i dont have a tune, and i really havent had any issues outta the tranny before like no slipping or anything.

How heavy does your right foot weigh? You need a tranny cooler at the very least, bro

occasionally a tranny makes it off the line and fails soon there-after

sounds like you were the unlucky 1 in a million

[skeet]

it happens !!

be greatful it happened why it was under warranty

[TvsQuez]

many nnbs trucks have had tranny problems. Welcome to the club, and keep it warrantied.

i guess so.. oh well glad it is under warranty.

ive been lucky that nothings gone wrong with mine...and with the added power...uh the dealer will not warrenty a 400+hp 6.2 lmao but it's ok...either a built tranny or a 80e swap is in the future anyways

It sounds like the input sprag has failed in your transmission. Vince
