I feel the transmission may be giving up the ghost.

A couple months ago it gave me a transmission slipping code while towing a car. I reset, and have not been using OD. Haven't had an issue with that code since.

However, now there's a new issue. I plow with this truck, and need to reverse for extended periods of time/distance. When I do so, the truck does not want to go back into a forward gear. It started out that I had to drop it in to "1" in order to get it to catch a forward gear. Once it catches, it's fine. Shifts normally through the gears. Well, once time it didn't want to catch. I had to rev the 7.3 to ~2500 to get it going in a forward gear (while I was in "1")

I stopped reversing for long distances, and didn't have the problem again. Tested it out one more time by reversing for ~100', and had to drop it in to "1" in order to catch a forward gear again.

Is it a valve body isses/servo pack? I'm not getting any errors/codes.. Man, I miss my manual!

 

how's the fluid level?

 

Actually seems a little high. Think too much fluid is causing a problem?

 

pull the hose on your aux cooler and start it up.let it pump some out.try and get the level perfect and go from there.

 

Good tip, thanks. I'll get back to you with what I find. Might have some snow tomorrow night, so hopefully good results follow.
