Default Tranny issues when cold..

Tranny refuses to go into gear when cold. I can't even move the car in the morning unless the car has idled and warmed up for atleast 20 min.

I never had these issues in Hawaii. I'm in MS w/ 15 degree nights.

The car is fine in the day when I'm driving, but when it gets cold, I have problems.

If the car is in first, and press the clutch, and rev. The car rolls slightly.

Has anyone else had these issues?

Updated slave, master, and Spec 3 w/ 10k miles.

Any help would be appreciated.

My car does not like to shift into 2nd till I drive for a while, but seems you've got bigger problems than I.

Part that worries me is when you are in gear and have the clutch pushed and the car wants to creap. Master or slave leaking internally? Did this start the same time it started shifting hard? Makes sense that it could cause hard shifting.

If it moves with the clutch depressed, its not a trans problem. The clutch is not releasing. You don't notice it when its warm but the drag is still there. This WILL develop into a trans problem ( synchro wear) if you don't get to it.

Not to jack the thread but my car seems to have problems when the weather is cold as well. After it sits for the night I can get in and go like I always do but going into 4th or 5th it grinds. It only does this when its cold. Maybe we have similar problems.

Spec stg 3 + ugraded slave.

I had the same problem. I changed the tranny fluid and it hasn't happened since.

bleed your hydraulics....think of it this way when you push your clutch to the floor and it doesnt want to go into gear, your clutch is not fully disengageing thus the in gear clutch in gas it and it rolls theory.....couldnt hurt to try....bleeding only takes 10-15 min topps

I found the problem. Master cylinder resevoir was really low. I'm guessing we didn't get all of the air and what not out when we installed the clutch and updated master and slave cylinder. I'm going to rebleed the system tomorrow.

Mine does that going into 5th, but it doesn't happen very often.

OK. Here's my deal:
Alright fellas. I am having some major issues with Reverse, but only when it is cold. It keeps throwing itself out of gear and it's driving me insane. The only time that it will do it is when I slip the clutch and leave the clutch engaged about 1/3 of the way. If I fully disengage it, it will only do it 2/10 times. Like I said from the start. It only gives me this problem when the car is cold. Also, 3rd likes to grind when the car is cold as well.

Help please! You all think Ijust need to replace the transmission fluid?

Mine has been doing something very similar to this after getting a new clutch installed. The problem looks like it's the master cylinder just not getting enough pressure built up, but the shop who put in the clutch (along with a new pilot bearing, throw-out bearing and flywheel) is looking at it right now. If it turns out to be a bad slave cylinder, I won't get charged, but if the master cylinder is on its way out (87K+ miles on the stock clutch and hydraulics), then it's out too, but I'll have to pay for that.

Just curious, but what happens when you pump the clutch a bunch? Do the shifts get easier? I figured out mine did, which led me to a hydraulics issue.
