M1009 Transmission Issue - newbie

[Whit]

Hi Folks.

Newbie here. Just became the proud owner of a M1009, taking delivery Monday night. Went for first test drive last night and the transmission does not shift out of first gear. Reverse works. The problem is when in Drive it will not move out of first to second or third gears. The fluid looks clean and pink, at the right level. How do I troubleshoot and (hopefully!) resolve this? Thanks in advance!

Keep revving it and it should shift around 3000 rpm, if it doesn't your looking at the governor or valve body. If it does check for vacuum at the modulator and the valve on the side of the injection pump.

Here is a previous thread with some info... http://www.steelsoldiers.com/cucv/52443-shift-issues-m1008.html There are others that I read to fix a similar problem with my M1009.

The search function will become your best friend on this website. There is tons of good information just waiting to be discovered. I use the advanced search putting in a key word or phrase then pick the appropriate forum to search in... in this case "Vacuum regulator" in CUCV forum.

Welcome to the site.

It could be as simple as the vacuum hoses that feed vacuum to the transmission.

There is a short one that links a hard line to modulator on the side of the transmission. Trace that hard line back up to where it changes to rubber again. Replace those lines no matter what but that simple act may fix your issue.

Ta Daa! Fixed it!

Thanks for the responses, gents. I also searched around on old posts and got eddicated a bit. I replaced the vacuum lines and the modulator valve, and the tranny shifts! What a relief!

Next will be to adjust the VRV to get it to soften the hard shifts up a bit. Then start working on replacing hoses and belts.

Looks like the bushings in the front end are pretty dry rotted too: there's another project, probably a several-beer one.

Hey, this thing may be ready to roll by the time I get my SF97!!

Anyway thanks to all.

Not to point fingers or name names but you might want to check the wheel bearings too...
