Ok here is the problem... I have done nothing to my truck, the way it is is the way I bought it. The problem is when I nail the go pedel to the floor nothing happens... other than the engine spooling to high hell and me noth going anywhere!!! Im at a loss. This is my first diesel and I dont know ***. Things I know of are the banks tq converter and the banks six gun that is not even attached to a pda so I assume it's off. I have what seems to be enguagement in the tranny up to about 3/4 pedal and after that it just lets go and she does nothing but rev. Regular driving is great. Any help or suggestions would be greatly appreciated.

 

Sounds like your trans is slipping bad!! Drain you trans fluid and take a look. If it smells burnt or you get all kind of goodies in the fluid, then you just may have a bad trans!

 

had the trans out 4 months ago no burnt fluid, no goodies, and the re-fill was all bullydog fluid. I pulled it out to replace a "stock" tq converter and thats when I found the banks unit. nothing changed from removal to re-installation.

 

Does it slip at WOT but low speed? Put a trailer behind it and try under load? If the engine is revving up but not going anywhere, its gotta be the tranny (or TC). Everything else is hard connected.

only slips past 3/4 throttle no matter what.
