Here's the email I received back from these guys the Trans Exc...all that's required is disassy. of the AutoTrac case and toss in this input gear. Hell, I don't see why it wouldn't work in place for the SS guys too with the AWD case. This piece is for like a 32T output that the 4L80E has vs the 27T the 4L60E has.



Hi Eric, our part # is GEA 19019. I believe that the OEM GM # is 12386258. This input is available for $106.00 + $11 S/H = $117.00.

We accept paypal,
Visa/MC/Disc/Amex (call toll free 866-847-5051 or 800-776-1191 ext. 79), money order, check (must include drivers license # and issuing state with check), and cash (at your own risk).
Thanks,

Some of the 3/4 tons already have autotrac, but good info nonetheless

I wonder if they have a way to convert a np241 from 27 to 32 spline... looks like it would be alot cheaper than buying a new case...

Yeah. I'm looking to put in a NV4500 manual tranny. Its got a 32 spline output, just like the 4l80e. The NP241 has a 27 spline input, just like NP246 autotrac case. I was just curious if I could do the same kind of thing to my np241...

I don't see why you can't get that input gear if the cases are physically the same. Would it be easier to just get the larger T-case for your NV4500?

Maybe easier...but I dunno about cheaper :bawl: We'll see... I'm not even sure if the bolt pattern is the same on the np241 as teh nv4500, and its too dirty under my truck right now to look.

Ah hrm, well don't be too hasty on your decision when/if you go with the big manual box. If may be smarter to wait it out for a complete 4x4 one.
