I am thinking very strong about switching to a ZF6 but I have heard that the trans hump is shorter on the auto's? I talked to a guy on TDG that has done the swap and says that everything fit fine on a 02'. So can somebody give me a credible answer as to f the humps were different between a auto and ZF6.

Thanks

Shouldn't be. IIRC the same driveshaft fits both, so what ever you use must add up to the same overall length. Hence anything around it must be the same size.

Are we talking about the same thing?
I am talking about the hump in the floor boards that the trans fits up in side of and on a manual, the shifter comes through it.

FYI: the drive shaft has to be lengthened by IIRC 3" for the manual.

auto will fit in place of a six speed
but a six speed is taller thus needing to cut out and reweld correct trans floor pan

I stand corrected.

Ok, answer this for me:
Is a 02' automatic truck have a DIFFERENT size or shape hump then a 99?

The big reason I ask is the guy I talked to that has done the swap before said the ZF6 fit right in there but it was on a 02'.

I'm thinking of doing the same swap... I've been told the tcases inputs are different too. From what I was told there are two different zf's and each are a different spline count than the auto.

But I have not got a straight answer on either issue... doghouse and tcase. oke:
