Non-thirdgen: Transmission problems

[Ward]

Well, my buddy's 98 Cobra is having some trans problems, and we're not exactly sure what it is. Sometimes it grinds going into 2nd, 3rd, and 4th(Tremec T-45). If it doesnt grind in 2nd, then it wont in 3rd and 4th. Also, it only does it when upshifting, downshifting is fine. All 3 started doing it at the same time too, so I wouldnt think it could be the synchro's, but I could be wrong. Any ideas?

Junk it and buy a third gen?

[Nexus6]

clutch maybe? ,maybe the clutch fork?

[BADB0Y]

Seriously it does sound like either a clutch or maybe just a clutch adjustment problem.

Might be the shift forks inside the trans.

Well, since most of it is the same as a T5 and I have seen this problem. The syncros are getting tore up. Caused by three problems:

1) Clutch getting it not getting disengaged all the way. This happens when people don't know the proper way to shift and take off from a light (burn to much clutch). Also possible that the pedal is not adjusted.

2) Shift forks are worn out or partially bent.

3) Too much racing and hard throttle have damaged the syncros.

The adjustment of the clutch pedal should be self adjusting, look in the manual or a shop manual to see if it is. The way to set the old fox chassis mustangs is to push it to the floor and release it as fast a possible. You can always press it in and slide your foot off of it. I think it is three times or something like that. Let us know what you find out.

He hasn't driven it really hard, few races, but the previous owner probably dogged on it pretty good. When he got the car, it already had subframe connectors and nitto drag radials :P It also has a steeda clutch cable adjuster (installed by rpevious owner). Could it maybe be improperly adjusted? I was kinda thinking something with the clutch since it is doing this in 3 gears and they all started at the same time. If it was snycro's, I would think that only one gear at a time would do it.

Good point, probably not the syncros. I would have to think that the first guy dogged it then. It would be hard not to, and have nitto dr on it.

The clutch might just be wearing out, and that is why. Anyone that I do tranny stuff with, I always tell them to get Centerforce Dual Friction clutch. I haven't trusted anything else.

If I were him I would take out the tranny and inspect the clutch disc, it would only take a couple hours to do, but then he would know the truth of inside the tranny or if it was the clutch/throw-out bearing.

I have the Centerforce dual friction on the B4C and it works great, ask Erik about how hard it grabs.
