Mark,
It may be a defective or dirty vacuum controller on the side of youe 6.2L
injection pump. I had erratic shifting on my M1009 once and I removed,
cleaned, installed and adjusted the controller and that cured it. Mine was
either shifting too early or too late causing a "slipping" or "banging."
Check yours and that may cure your problem. It might be getting heat soaked
after shut down. Also, you may remove and check the governor on the side
of the th400. Mine failed and it wouldn't shift out of first no matter what
the rpm. Maybe yours is failing and tranny heat makes it worse? Good luck
and let us know what you find out.
Chris

IM having troubles with my CUCV Transmission shifting correctly.
When i first start up the truck and take off in it, the tranny shifts just
fine, just like a good working trany should.
Now for the kicker, When I shut it off after the initial first start run,
and get back in it to go again, It shifts very hard, it will shift from 1st
to 2nd gear at 25mph and then from 2nd to drive at about 37mph and you think
its going to snap your neck.
Now I have replace all vacum hoses, new vacum modulater on trany and it was
suppost to have been flushed and seems like the vacum pump it working fine.
Does any one have any ideas as to why this might be happing? I think I will
change out the trany fluid and filter myself, but why the hard shifting
after warming up and being turned off?
Thanks
