BAD2THEBONEBLACKSS Posted September 13, 2006 Report Share Posted September 13, 2006 Has anyone ever thought about replacing the automatic tranny with a 6 speed? Just wondering if it would be possible . Quote Link to comment Share on other sites More sharing options...
misterp Posted September 13, 2006 Report Share Posted September 13, 2006 (edited) Yup, there's nothing like rowing your own. A Keisler 650hp T56 would be a dream. Switching over would not be that bad, you'd have to find a donor base model Silverado (with manual shift) in a wrecking yard and get the steering column & pedal assembly; although there might be a difference in the wiring harness to the column but aside from the neutral safety stuff I seriously doubt that. A couple PCM tuning changes might have to be made. The hardest part of the entire swap IMO would be figuring out what to do with the center console (who the hell needs cupholders ) although a creative person with time/money could fab-up a suitable replacement.

SSLink Posted September 13, 2006 Report Share Posted September 13, 2006 That new 6 speed auto might be a nice swap if it mates up with the AWD xfer case OK. I bet Zippy would know... Quote Link to comment Share on other sites More sharing options...

Mr. P. <{POST_SNAPBACK}> Isn't the case longer on the 2wd 6 speed tranny vs. the 4wd 5 speeds? I thought 4wd transmissions were shorter???

montanass Posted September 14, 2006 Report Share Posted September 14, 2006 who cares... just make the tranny fit and then fit the driveshaft's to the proper length... Quote Link to comment Share on other sites More sharing options...

You're talking about moving the transfer case back and getting new driveshafts made, but there's quite possibly a lot more to it than that. If the trans doesn't have the same output shaft diameter/length (which it most likely doesn't), a new one would have to be made. Trans to transfer case bolt pattern is most likely different, which would require a machined adapter plate to mount the cases together. Custom trans mount/transfer case mount to mount them to the chassis. Quote Link to comment Share on other sites More sharing options...
