Wondering about this problem:
644C was working fine until the last time I shifted into high range, the transmission pressure gauge went to zero. Normally, the guage drops pressure when you shift, but quickly recovers. Low range still does this, but when you shift into high range the guage goes to 0 and stays there. I could still move forward in high( if I wanted to risk it).
Anything to look for short of pulling the tranny?
