I was running strong from 1st to 2nd, then missed 3rd and went right to 5th. No grinding, no strange noises. I ended up trying to downshift, and it would not pull out of gear. Pushed clutch in several times and it feels like I have normal pedal, but it will not disengage. I shut it off and can shift gears. Ended up starting it up in 2nd gear with the clutch in and drove home. When I got home I did downshift to 1st and it went, but clunked in like I did not have the pedal fully engaged.

Any Ideas what it is before I have to put it in the shop. If it is an easy fix, I will do it with the tranny in. If not, I have to remove the motor for an oil leak and exhaust gasket change anyway.

Sounds like the clutch is not disengaging fully. Check the clutch fluid level (gets fluid from the brake master), clutch master and slave cylinder. You can have a friend watch the slave actuate the clutch (car on jackstands - doesn't have to be running) through one of the inspection holes. Some have broken the aluminum clutch release fork. If the above are ok, that is the next place to look.

 

The good ol argument of auto-v-man bet right now you wish you had a auto.

Check your shifter fork, depending on how hard you were banging gears you might have bent your fork. I bent my fork in my Jeep when I banged 2nd real hard, it was fun when the wheels came off the ground but insted of fixing the tranny I put a C4 in it. Yep the ol auto-v-man.

I prefer auto's it seems, in racing you have no slipped cluthes, missed gears, bad launch's, and in 4X4's you dont have to heel towe.

my 2cents, and it aint worth much. Good luck.

 

you might have damaged your synchros as well...my missed shift to third a few years ago lost my fifth and reverse completely.

it does sound like a broken or bent fork as well.

fukk automatics.

Awww, where's the fun in that? I happen to enjoy heel and toeing, gotta love the sound of a blipped rotary going into my favorite offramp.

Good luck with the tranny Tim, not sure what happened, but if it still works it can't be too bad right?

 

I agree with SVT Squasher. If you were shifting really hard and really fast and missed you easily could have bent a shift fork, busted a dog ring or possibly hurt the interlock mechanism.

You didn't harm the clutch, they don't just break from missing a shift.

My advice is to pull the tranny and open it.

 

I agree it sounds like a bent/broken fork perhaps. But the more likley culprit I have seen is the 5th reverse slider gear and synchro. Just had someone out here do a similar thing. Won't go into 5th or reverse after he missed third dragging. ...... And on a side note,.. autos have there place....Just NOT in a sports car!!

 

Definitely. I just put in a JUN 8.5 chromoly flywheel and the Pineapple 6-puck and the rev response is how it should have been from the beginning.

The sprung 6-puck is chalking up to a lot of fun in traffic (read: it's a bitch!).

 

How bad is it?

 

It's Cast Iron! Not Alum.

 

Damon,

Still breaking it in, but the only issue is 1st gear starts. One just has to get over the desire to want to slip the clutch and just do a more binary engagement instead.

 

a friend and i took apart his tranny to find out why it was stuck in 5th....

i'm unsure about the correct jargon with regards to transmission parts, but after we took off the housing, we saw that the shift fork had slipped out of reach of the selector linkage hooked to your shifter. A rollpin had popped out, so the fork rotated around and the shifter could no longer 'grab' it to pull it out of gear.

Does that make sense to anyone?

Hopefully that's all that happened!

Good luck.

 

i had this happen not but a while back in a jeep but i was going down the highway in fifth and i got off the highway to find that it would not pull out of gear very easy i pulled it as hard as i could and i came out with a clunk then tried to put it in another gear and wouldn't every time i putit where a gear was it would clunk in the rear end. i drove it about 4 miles starting out in forth. found that the clutch fluid hadn't been changed in a while and the hose was clogged.

 

The clutch fluid is fine, I have not gotten under the car yet, but have had slave cylinders go bad before. It is not the same. I have full pedal feel as if the clutch is being pushed in and out and have a considerable amount of resistance because it is an ACT clutch. It does shift into and out of gears when the engine is off, but when I start it up even with the clutch in, it is in gear and starts moving.

I am leaning towards a clutch fork problem, but if it broke, would i not have an easy time pushing the clutch pedal in and out? I am leaning towards the pin theory also. I have rebuilt a tranny in the past and recall the same problem in another friend's car.

I don't think it is the synchros as I rebuilt a tranny due to synchro's and they grind prior to being bad. No grinding whatsoever happened. I just missed 3rd and into 5th. When I let the clutch out, the rpm's dropped considerably more than expected and I realized I was in 5th gear instead of 3rd. No problems for about 1 mile before I tried to downshift to 4th, then it would not come out.

Could I have bent the fork so it does not travel nearly as far as needed?

PS one thing I left out. This was a tranny from a rear ended car. The driveshaft was smashed into the rear seal, but did not damage the rear housing or driveshaft. Replaced the seal. No other visible damage.

Also I noticed when I started driving the car after the tranny swap that 1st to 2nd under hard accelleration appeared to be locked out. It would go to neutral and stop completely. Smooth shifting under normal conditions. Also noticed that there are times when the clutch grabbed much sooner than I expected, then later would feather out from a stop like normal. Possible precursor for problems? This tranny was suppossed to be rebuilt professionally or at a minimum replaced 5th gear synchro assembly.

I also have synthetic Royal Purple in the tranny and cold starts seem to have a difficult time shifting in and out of 1st and 2nd when cold.

 

This was an auto to manual conversion car. Pulled the engine and tranny out complete from a donor car and installed in the auto car. 5 speeds are by far much MUCH better in the long run. For instance, if this were the auto locked in a gear, I doubt I would be able to get home. I just started in 2nd gear and ran home about 40MPH

 

It's jerky as hell...tough to engage smoothly from a start. I watched him do the jerky starts last night after getting it from the mechanic. Hilarious, for me

 

I know this is an old post, but FYI, the pilot bearing locked solid to the input shaft of the tranny. When I moved the car, I started it in gear, The jerking of the car trying to start in gear freed up the bearing again. It ran fine until I locked it up under hard accelleration again, this time in 2nd gear. Ended up jerking it back and forth again and it freed up.

It was the pilot bearing, nothing else.

Thought people should know just in case this question was researched.
