Car gets harder and harder to shift into gear

The problem started about 6 months ago (6 months after replacing my clutch). After driving for more then 20 or so minutes of standard driving or 1 minute of aggresive driving my car gets very very hard to shift into gear (sometimes it just doesnt happen at all though but usually always if im on the highway for an extended period of time ). For the first twenty minutes though it works perfectly fine and shifts like a dream. This problem started with first gear and only happened on occasion. It then started to happen more, and more, and more, and more and started spreading out to my other gears and now happens to all my gears. Sometimes i cant even get it into reverse.

I have a very small leak in a switch on my transmission switch it doesn't even drip it just gets a little wet around the area. This could be the problem but im not sure.

Thanks ahead of time for the help!

I plan on selling my t-5 soon swapping in a T-56 so any advice how to keep my transmission working until then would also be appreciated (if it happens to be a syncro problem or something that costs any significant amount of time or money).

Re: Car gets harder and harder to shift into gear

Im not really an expert on this stuff... but it sounds to me like it might be clutch drag. As if the clutch isn't completely disengaging. And because of that it's probably chewing up your snychros and gears.

But I dont know... just a thought.

That is exactly what it sounds like. Now if I am not mistaken you have a hydraulic clutch, see if there is any air in it. something is not letting the clutch to disengage completely

Centerforce clutches don't work in third gens due to the rubber line connecting the clutch master to the slave. When revved up the centrifugal weights require extra pressure to disengage the clutch and instead of the clutch disengaging the rubber line expands. The clutch only partly disengages making it hard to shift gears and blowing up transmissions.

try getting a steel braided line.

Will it actually expand that much? I know it will a bit but not that much

Re: Car gets harder and harder to shift into gear

I had a somewhat similar problem once. The bolts holding the tranny to the bellhousing came a little loose. I tightened them up and it fixed my shifting problem. Just a suggestion.

Hmm interesting. Well seeing im putting my car in storage for the winter in 2 weeks and putting in a T-56 when i take it back out ill just leave it as is. How much damage do you think it could have done being in my car for a year.

Probably not allot if you weren't to rough with it, you might have tore up the synchros a little, I'd get a steel braided line and see if it helps there not that expensive.
