Hello ya'll 1st time on site I have a '93 f250 4x4 7.3 zf-5 4.10's If rolling forward , or stopped aimed downhill will not go in rev. if it aims up or bump against curb etc. goes right in no grind temp/drive time not differance ,only had about a mo. 300,000+mi. I was told. Any help would be appreciated Thanx!
have thought about that , no issues in forward gears though , I do have cl/brk bushing set just not installed yet lot of slack in linkage ,crossing fingers on that ,just did'nt know if this is a common problem (rev.)or not Thank You.
I trick I just learned about ZF5s is to ditch the ATF from their case and fill 'em up with motor oil, 30W for time being, they can tolerate up to 50W. You need straight oil too, not 10W30 or something of that sort, just SAE 30 and if that don't elp SAE 50. Don't know why that works, but sometimes it does, so give it a shot.
My manual for the 97 says you have to go to move the left of third and fourth before going into reverse.

Well , I changed the clt/brk pedal bushings ,helped ALOT but will still grind & not go to rev. sometimes pumping clutch will help(after changing bushings) may have to plan on total clutch &assy. replace . Does it matter 30w. is detergent or non-detergent? Clutch will have to wait abit wonderful ex-wife can't wait to cost more money LOL!Thanx for info.
