Transmission Fail

[Tub Asko]

First I have a:

97 GMC Sierra Ext Cab 2wd

5.7 with a few mods

Rebuilt Transmission as of 2 yrs ago

Fully Bagged and lays frame

Well my transmission started slipping . . . so yea I have to get it rebuilt apparently. But the guy at the shop told me I probably have to get my drive shaft shortened because it's in a bind against the transmission.

Well considering I have many more performance upgrades planned and possibly a 454 swap in the plan I would like to know what a good performance transmission would be (like some links!). I already have a shop lined out to shorten my drive shaft. So instead of rebuilding a crappy stock tranny I'd be more comfortable shelling out the few extra bucks for a better one.

i've heard good things about bowler transmissions, you need to call for the price.

this will be a direct swap.

The bottom brace that holds the driveshaft in the middle Tub, did they put spacers under it to lift the shaft, if not it will be a reason why the tranny failed after 2 years. On mine when we dropped it 7 in the rear we had to cut the bottom of the truck brace cause it sat on the drive shaft.

Do you get any type of shimmy's when you excelerate from a dead stop?
