gear box troubles

A good place to get an answer would be the "Patrol" forum who specialise in these.

Apparently they did have this well known problem.

Can be caused by towing in 5th.

Good luck

You will probably find you have stripped the spline on the shaft and more than likely in the 5th gear[ been there done that ], cost approx $1500 make sure you get the shaft and gear replaced with the later shaft which has a longer and heaver spline.

If my memory is right they are a Supra gearbox is this correct ????

Hi Duane
If he has lost 5th and reverse only, it is not likely to be a stripped spline etc. I would be looking more at the shift mechanism. From what I can see in the manual, reverse and 5th have different shift forks but has a common fork rod. This fork rod is bolted to the reverse fork and if this bolt has broken then you would loose both reverse and 5th.
I do not know if you can get to the top of the box through the flloor or not but either way, I would be removing the top of the box to have a look as it may be a simple fix.
Reverse, 5th and the shifting mechanism is housed in the rear OD housing, which looks to be easily removed without having to touch the rest of the gear box.
