Bolts for Transmission support to trans case

Does anyone know the correct dia and length for the two bolts that go from trans support into the trans case? This is on an 82 X with 5 speed

I have my '83 apart and it uses M8 x 25mm with a captive lockwasher.

Trans bolts

Thanks for the info.

M8 x 25mm long, grade 8.8 Hex Head Cap Screw, NO "lock washer"

*Note plotted results, actually worst than no split lock washer.

Split lock washers do little if anything to increasing the tendency to loosen.

*There is a M8 stud at one of the Transaxle mount holes. It is important to know this stud goes directly into the oil area inside the transaxle. If this stud is replaced with a screw, there will be a tendency for that are to leak transaxle oil. Do not remove this M8 stud without knowing what can and ill happen.

Hi Bernice,

can you explain (preferably with a photo) the location of the stud that you are referring to. I do have a small oil leak in this area and just wanted to confirm the stud in question.

The forward most hole is always a stud.

It's actually a blind hole, but is directly in line with the selector shift rod.

If a bolt is used that is slightly too long, it will bottom and force the alloy to bulge inwards into the selector shaft bore, and cause the casing to pinch the shift rod during operation.This will gouge the selector rod, finally making shifting harder and ruining the selector rod and the transmission casing.

Thanks Steve,

all good then. Stud in question is this one right?



Cheers,

Yep, that's the one...the same for four and five speeds too.
