Play nice Sargent!!
I sell nothing in the oil, lubes, or greases.
Sorry to say if you do a little research the GL5 gear lube is all over the Jeep as well as other help forums causing issues and failures with manual transmissions.
I am researching a toyota clutch currently, 150k miles, to see how long they last and there are posts there about the GL5 there too. Countless other forum sites too.
Even the GL4 bottle says not corrosive to yellow metals. wonder why???
I have about 3 years of hard research on this GL5 and GL4 gear lube for manual
Transmission . Have read everthing I could find on the subject.So pretty confortable in what I have posted.
If you have some research you would like me, and the other memebers to look at, please post up.
The 1982 Jeep FSM and the full model recal to replace the GL5
Transmission lubrication that was causing
Transmission failures would be a good place to start research sargent. GL5 issues are real and affect many of us.
AS for this Thread... I was reading thru the pages of posts and saw this post that had been sitting for a month and not been addressed. Thought I would help out.
FURTHER THINGS FOR THE POSTER ASKING FOR HELP TO CHECK...
The clutch pedal free play should be looked at. I think the spec is 1-1.5" of clutch pedal before feeling resistance at the top of pedal. Put your foot or hand on the clutch pedal, push down, pedal should move the 1" or so before more resistance is felt.
Have a friend work the clutch pedal while you look from under the car. Should see a full stoke on the clutch fork looking on the side of bell housing. At the same time look the mechanical linkage on the lower firewall. There are pivot points the come loose, wear and cut down your throw / movement amount.
Poster did not say he changed
Transmission lube...... but I have seen dozens and dozens of these fluid situations. My first guess is fluid related, second guess would be a linkage. Linkage would affect all gears more.
