Hi guys, first post here.

My '93 RX-7 was down for several months for a engine rebuild. It always shifted fine then... but now, after it has heatsoaked for a while, it becomes very difficult to shift into 1st, 2nd, and sometimes (although not as often or as bad) 3rd. The clutch engagement point doesn't seem to change; only the shift effort gets very high.

When cold, it shifts smooth as silk. No change here.

Background: when it first started happening, I replaced the slave cylinder. Still hard to shift when hot. So I replaced the master cylinder. No improvement. I then replaced the clutch hose with a stainless braided line. No improvement. Bled the clutch. Again. Still hard to shift.

So now I have a brand new hydraulic system and the problem persists.

Could the car sitting have caused deterioration of... something? If so, what? I'm at a loss here. Need some help. What would cause this behavior?

 

maybe ur synchros are f*cked up.


tranny rebuild time, $1,000 bux. not bad investment. I gotta do mine in a few months.

 

i had that problem kinda. My car was siting for about 4 months and when i got in and tried to moved it, the shifing was very stiff. I check the fluids and toped it off, and without starting the car i just played with the shifter for about 5 min. 1st all the way to 5th and back again. From start it was very tuff to move then if started to losen up so try that. GOD bless !!!!

 

when was the last time you changed your tranny oil?

 

^^^Exactly. The fact that it got worse as it heated up is a sign of a lubrication problem.
