Started asphalt today, was hauling gravel, no issues other than the box hanging up sometimes going from direct to reverse. 5x5 trans. today, backing up to the box, when i took it out of reverse to neutral, got ready to lift bed, smoke started billowing out of breather, could not raise bed, i then put it in direct and 1st to pull out of the box, truck went in reverse. it caused my motor to run backwards. I have to shut the truck off, in neutral, restart put in direct and it works fine.
made some calls and apparently the aux box parts are obsolete, called a guy who has done a ton of fro swaps in these trucks.
My question is, why/ how is it locking in reverse and why is it causing my motor to run backwards?
thanks for the info!
