Reverse gear (Page 1/2)
M.aaron80 MAR 14, 10:01 PM
I have a 86 gt 4 sod. I did a getrag 5spd swap. All gears work but reverse.no grinding or weird nosies. I did see the master cylinder has a small leak behind the pedal but clutch pedal still slightly firm. And the rod in the slave cylinder don’t seem to be moving. Could be worn out slave?

If you have the original 4 speed shifter you need to remove the reverse lockout mechanism from the shifter. If all the gears work without grinding or having to push really hard to go into gear with the engine running you do not have a hydraulic problem.

I don't understand how any gears "work" if the slave isn't moving.

Yes I have the original 4spd. and I have the 5spd floor shifter installed. Yes this is throwing me for a loop about it working

Ummm... I think we've got us a communication problem here.

There's no way ANY of the gears are going to shift properly while the engine is running if the slave isn't moving... unless the clutch is somehow stuck disengaged.

*UPDATE* slave cylinder does seem to be working but the rod inside of it is not fully extending. Maybe this is because the leak in the clutch master cylinder? Also I did not have the rod that came with the with the 5spd slave cylinder so I used the rod from the 4spd slave. Any difference?

The slave rod on my 86 only moves about 1.25 " roughly. When the hydraulic system developes a leak it usually causes more air ingress than fluid leaking. But the air in the system is what causes the rod to not move very much. Pitting in the slave cylinder bore is what causes most air ingress.

I have a new clutch master on the way. The rod moves about half inch. Is the 5spd shifting pattern 1 3 5 on top row and 2 4 R for the bottoms row?

*UPDATE* if I push the lever for the cable that moves side to side it will go into reverse gear. Clutch master cylinder has been installed. I did buy the slave from Facebook market. The rod inside of it is only moving half inch
