NV3500 direct replacement? Howdy,
I have a 2003 S10 xtreme that I LS swapped and I want to switch from a manual to an automatic. I just had the driveshaft rebuilt and don't want to change it, also don't want a computer controled trans.
I believe a TH350 has the same yoke but the TH350 comes with a 6 , 9, or 12 inch tail shaft.
What length tail shaft TH350 do I need to replace the NV3500 5 speed that is coming out of the S10?
What TH350 is the same length as an NV3500 5 speed?

The S10 also cam with an automatic trans, the 4l60E I believe, perhaps someone knows the specif length TH350 that would replace the same length 4L40E from an S10?
Is it safe to assume that the NV3500 is the same length as the 4L60E??
Also anyone running a NV3500 have the same issue where it won't go into the next gear if spinning the engine to 6K?
I've had a couple NV3500 and they simply don't like to shift if they are revved higher then 4,800 RPM. I assume its just the design, that they are not designed to shift at high RPM. Or did I just happen to have a couple really worn out examples?

I got you chief. My buddy did the opposite direction of this swap. Went from th350 to nv3500.
He told me his original th350 tail shaft is 9"
He said you would have to move your crossmember forward a few inches and drill new holes.
He did his on a C10
Hope this helps

I did try to research and that's pretty much what I thought but I could not get confirmation anywhere....I got pretty close, one post mentioned something similar - the "long tail" TH350 but they also made a 12 or 13 inch tail shaft so even though I knew the "long tail" was what people commonly referred to the 9" tail I didn't want to drop the $$ and find out actually....they were talking about the rare 12 or 13" er
Thanks again
