Looking great! You are doing solid work for what appears to be a fairly small shop, I know the feeling well!

Thanks! Its a 20x20 this weekend I hope to get the 7' 11" truck out of the 8' garage door. I really could have used a bit more room during this project, but I cant move until the truck is back on the road.

I ran into that problem before and ended up having to air down all of the tires to get it to fit! Good luck.

Big progress but not alot of pictures since its been dark when I get home. Got the front end and bed on. The passenger fender to door alignment really spun me for a loop. Apparently I needed a spacer under the front passenger side of the cab mount (luckily found it laying on the old frame still!). Spent a good 12 hours on it.

Replaced the lap belts with three point belts from the other truck. Just had to drill a new hole in the floor.

Rest of those pictures.

I got to take the truck out for a spin but it wont shift out of first in d or manually (reverse works). I've tried just about everything. I have vacuum at the modulator, I replaced the modulator with another I had, the kickdown solenoid (that I just replaced) clicks when supplied 12v, tried running with the kickdown solenoid unplugged all with no difference.

I did install the new kickdown solenoid using the original metal gasket which I am beginning to think I should not have used and could be my problem.



Gotta drop the pan again.

It will give me the chance to replace the leaking trans cooling line and speedometer gear. I got a deep transmission pan with a drain plug on it in case I need to go back in again.

Otherwise the motor seems to be running great.

Removing the kickdown solenoid gasket didnt solve anything. Trans fluid had a whole lot of clutch material in it for driving it around the block.

The transfer case fluid had some water in it and rust (I should have tore it apart before...), I found some ground teeth and shift rails are kinda chewed up.

What to do.. after about a month or so of going over my options I decided to go with a 4l80e and rebuilding the np205 (I have another np205 to scavenge some parts from) with a twin stick. I picked up a 4l80e from a 2003 savanna with 163k on it, hopefully its got a couple more miles left on it.
