Hey Everyone!
I've been working on swapping a new transmission into my truck.
The marginal V-6 manual finally took a dive on me, so I took care
of it. Over the past three weeks.....count em'....3....I've been swapping
out the AX15 with the...get this....a NVG 3500 from the V-8's. I've also
included a V-8 clutch to go with it. I'm not quite done yet, I still have
to
reinstall the box and get a driveshaft made, but here's what I found so far:
1. The conversion is relatively easy. Both engines have the same
RFOB (rear face of block) and the same input shaft splines.
2. To put the V-8 clutch on the V-6 flywheel requires having 6
new holes drilled and tapped since the V-6 is a 10.5" clutch
and the V-8 is an 11"
3. GET THE SAME YEAR TRANS AS YOUR TRUCK. I have a
97 and it used a different speed sensor type than the later
ones.
Most of my time in this project has been eaten up by trying to
adapt parts from the AX-15 to the NVG 3500. The later computer
reads the speed from another source in the truck and the
engineering
staff eliminated the in-transmission speed sensor. So they
deleted
the output shaft gear and filled in the boss in the case. I had
to steal
the components from the AX-15 and adapt them so I get the same
type of
speed signal. I completely dissassembled the NV box and
machined
the output shaft, the back half of the case and the speedo gear
to
make this work. Not a lot of fun, but I saved a TON of cash as
I got the
NV box free.
4. The V-8 output shaft splines are bigger that the V-6, so either
you need
to buy a V-8 driveshaft, or have the V-6 shortened and a V-8
yoke added.
So, after I'm done I won't have to worry about the strength of this
transmission.
Now, if I only had a supercharger............hmmmm
