I have been searching and searching for a answer to this issue.
Just bought a 1990 4.2 AX-15 with 132K
The problem always seems to show up after driving 5-10 minuets. When Cold she shifts into all gear pretty normal (little more resistance than it should be but still drivable).
Once warmed up it starts acting up! I will be driving normal and try shifting into say 3rd when it will not go in gear with clutch depressed, will try 4th or 2nd, still won't go in gear, now I'm messing up traffic!I frantically Pump the clutch and hear a bang/clunk (from clutch) then try again and it often will go in gear.
Other times it will just grind like crazy only in 4th or 5th as If I didn't press clutch. I already bleed the clutch, peddles not floppy that part, no leaks visible from the master or slave.
I can replicate the bang/clunk sound when I come to a hard stop in neutral or if I open close the throttle in 1st or 2nd at higher rpms it makes the clunk sound as I rock back and forth.
All this when warmed up!! She drive fine cold, people test her cold and ask me ''whats wrong''. Something is very wrong!
While changing all fluids I found WATER in gearbox,transfer case and front dif, what a nightmare I know
. Many oil changes later they are clean but maybe this is part of the damage.
Any advice? Pull the trans out? Clutch?
Thanks for the help
