Reverse Problem with FZJ80

[wampiFZJ80]

Yes, I tried the reverse and it works perfectly. I also noticed a great change in the in the other gears. Before, I coud feel that it was a little bit hard to reach some speed. Specially in the freeway. Now, the truck response a lot better and feel smoth.

reverse slipping, need some advice

I know this is an older thread, but it best describes what almost got me stuck up in the foothills yesterday in my 96 LC. Did the mechanic explain what exactly was wrong? Mine is slipping in reverse and in sand on a gentle incline I couldn't back up. The engine reved but wouldn't give any power to reverse. On the drive out I noticed that at highway speeds on hills it was weak. The idle also dropped at stop lights to where the engine shuddered a little. Don't. Know what the connection is, but they all seemed to show up together. Thanks for any advice I can get.

With cruisers I've been around when it slips mainly up hills in reverse.. ease into it or wait a couple seconds before moving... On trails if my centers locked it won't slip

Thanks. I'll give that a try.

Definitely not normal.

First thing to do is check the fluid level and condition. Next would be to drop the pan and clean/inspect the filter screen.

Oh, and were you in Hi or Lo?

My '97 does similar strange thing - sounds like a zipper when you try to go in reverse against a heavy load in 4Hi. No sound if I were to do the same thing in 4Low. Sounds awful but it has always done this. My '96 doesn't do this what so ever. This is a mechanical issue that I think has been discussed before.

That sounds like unlubed u-joints.

Nope.

Hi everyone. I finally got my truck back today after the mechanic finally found out the problem and fixed it.

Thanks everyone for your interest and help. Just in case someone else experience the same problem, I will ask the mechanic for an exact description of what it was done to my transmission. In the mean time, this is what he wrote in my receipt:

Rebuilt transmission and replaced neutral safety switch.

Thanks

i have a 93 with the same reverse problem you have. I honestly didnt notice it at all until i tried to reverse greater than 10 mph. what ended up being the problem for you?

Sorry guys, the 80 is too tall for J turns

Hello all, I need some help. I have a FZJ80 1994 and so far the truck is been great. However, I noticed that the transmission has a small problem. When I go on reverse and I push on the gas hard, the reverse disengages. The reverse works perfectly as long as I do not try to go fast. The rest of the gears work well too. I have been offroading with it and I have not had any issues.

I would like to know if anyone has experienced anything similar and if you know what the problem might be. Thanks for your help.

By the way, the transmission is automatic.

I have this exact problem, whenever I hit the pedal to the floor while in reverse after aprox 1k rpm the truck no longer accelerates and, when rpms go below 1k it resumes acceleration
