1985 CJ T4 transmission trouble getting it into gear

I have an 1985 CJ with about 200K on it. Since I had the leaking seals on the transmission replaced it has been tough to get it into first. You have to push the stick all the way forward and hold it there until it catches or the gears grind. Once it is in gear, however, it does not pop out. When you let the clutch out. This seems like it must be a linkage problem, but will take it apart tomorrow to see. Any thoughts on what else I might be looking for that could cause these symptoms?

Would prefer to be upgrading the transmission but will save that for the day when I have the time and the money to put a new engine in as well. For the time being, just want to keep this one on the road.

    did you get the clutch adjustment right after r&r?, Sounds like the cllutch isn't releasing all the way which would show up more at a standstill into first than it would while in motion (where if you're good at it you can shift without the clutch).

In your tranny u have shift forks that are attached the syncos that slide over the teeth on the side of ur gear. I think whats going on is that the little retainer sping inside ur synco in stuck not alowing the teeth to grab or the friction material is worn not alowing the first gear to slow down hope i helped u figure out the proplem.

Have an 83 cj 7, just replaced the power steering hoses. Thought I had fixed the problem, now the back of the steering gear box is leaking as well as the steering coupling boot is ripped. Don't really...


You can get the parts to rebuild your steering gear, but in all honesty for the trouble and time you will have invested in rebuilding the thing. If it were me (and beleave me when I say there was a time I wanted to do it all myself. up to and including manufacturing new parts from a chunk of steel) I'd go with a rebuilt steering gear. You can try to replace the seal but in the long run some thing made it give out in the first place.

Just my Service engine soon light is on for the second time and the code shows Torque Converter CKT Performance or stuck


The lockup function in the Torque converter is not functioning correctly. Your RPM's rise when you come out of Overdrive. Do you have the button in the shifter that turns ON/OFF the Overdrive? You don;t get it at startup since you can't go into O/D till the engine is warmed up-bet as soon as you go into closed loop mode (when the O/D can work)-the light starts. Hopefully it's electrical outside the trans-if it's the converter itself-the trans has to be opened. Check TSB on this problem. Ut has to do with a transmission oil pump defect and repair procedure.

This is something I recommend having a Ford Dealer do since they have the experience with the job.

When I start to drive my ford explorer the over drive light O/D come on and start to flashing. How I can fix the problem?


he overdrive off light flashing indicates that a problem with your
transmission has been detected. Take it to the dealer or a transmission
shop and get it checked out. If you continue to drive the Explorer with
the O/D OFF light flashing you can possibly damage the transmission.


Ford has issued a TSB on this problem. Has to do with a transmission oil pump defect and repair procedure.

I have 1985 cj 7 with an amc 20 rear differential, and i put a new axle kit and seals, but the right seal keeps leaking. what can be causing this problem?


By axle kit, you are referring to new bearing? I'd check the axle seal surface. Sometimes they wear beyond the ability of the seal to do it's job.If it's "borderline", I have had some success by filling the cavity inside the seal with black silicone sealer and letting it dry before installing. That helps keep the seal in contact with the axle.I'd also use some on the outside of the seal housing to prevent seepage there. Always use a small amount of grease on the seal lip when installing. Otherwise the seal can burn before lube reaches it. If that kit was not a bearing, replace the bearing as slight wear can easily open the seal enough to permit a leak. If the axle serves as the inner bearing race make sure that isn't worn either. There used to be an off-set bearing kit available for worn axles but not sure they made them for Jeeps.
There are several reasons an axle can leak. Not being able to see exactly what you are working with, I've pretty much covered all the things I'd look at and tricks I use to make things work even when they sometimes should not.
Hope one of them helps!!!

Sounds like the problem is in the speedo head itself, in the dash. If fuild was leaking, I don't think the speedometer would work either? Sounds like the gear that turns the number wheels maybe bad or stripped.
