80 Series With Slack in Shifter and Gear Slip

[BamaLC]

I'm sure somewhere in this forum someone has mentioned this before. My 80 has too much slack in the shifter or either underneath. It causes it even on rare occasions to slip into neutral if I accelerate too much without paying attention to it. I have replaced my motor mounts and I believe my trans mounts also. I am about to replace the shifter bearings underneath as I know those are worn out. It's just hard to believe that will be the final fix. It feels like there is something moving underneath but short of putting someone under there while moving I'm not sure I can see it. I guess I could also hook up a gopro to watch but has anyone else experienced this? Super frustrating feeling it when stopping and starting. I just have to baby it to make sure nothing happens.
Thanks for any help.

Currently waiting on this to come in and hopefully help.

It took a little over a week but the parts I ordered from Joey a month or so ago arrived with no problems.

@BamaLC I work in Auburn and if you want I can help you take a look at it, as can my son who works at Eagle Imports.

Be aware that this kit is for the floor mounted shifter linkage and not the transmission linkage, which could also be at fault. To get at that, you have to remove the pan and valve body. This also requires that you replace a crimped sleeve on the shift rod and replace two seals, one on each side of the transmission. I have one on my bench at the moment, and honestly I wouldn't want to do this from under the truck, even if I had a lift. Transmission shops do it this way, and they mangle the shift rod doing it. I have a mangled example to prove it.

This is the installation procedure:

What Toyota calls a "spacer" is a sleeve on the shift rod between the rod OD and the case ID. It gets crimped on with a punch (no lie). Getting it off without damaging the rod is the trick. The seals are included in the overhaul kit, but the spacer isn't. Transmission shops reuse them.

I'd love either of you to look at it. I have it at my office everyday. I do think it sounds more like the transmission linkage. I've used ACC in Atlanta for bigger stuff in the past so I'm interested in hearing your take on who to use to perform the work. Thanks. Steve

There are very thin plastic bushings on the automatic transmission shifter shaft that sits below the center console; IME if the shifter develops some slop replacing the bushings may help (but may not be the cause of your issue, read on).

Warning: IMO I would not recommend replacing them until you've first checked all the linkage bits etc and ruled out other possible causes of the shifter/transmission popping out of gear. The shifter bushings are a complete pain in the arse to replace (the OEM replacements break very easily, see link).

If you end up digging into the shifter assembly and find the bushings to be the problem I found a replacement made of RULON-J, very expensive but they did fit and that shifter is still snug, no slop (but then my shifter was just sloppy, it was not popping out of gear).

Has anyone replaced the shift(er) control bushings on a FZJ-80?

Got my shifter assembly out of the truck to do some service and decided to replace the shifter control bushings while I was in there but have been having difficulty getting the bushings and control shaft back into the housing. The tolerances seem too tight between the new bushings, the housing...

I may have time sometime next week M-W.
