DAMN, My 3rd tranny to break.

SE TRANNY - 1st Tranny broke 3rd
SE Tranny - 2nd broke 3rd.
GS Tranny - 3rd broke 5th ! ! ! ! !


WTF...Maybe the way I drive, but I dont power shift it.

Clutch 6 Pk w/ 3500lbs pressure plate Dual Friction.

Could this be the cause???


Anyone with input please..


Thanks

That and some sticky tires will do it.

 

These trannies aren't that easy to break. What kinda power does your engine make? Any mods? I've heard that they can handle up to 250hp on slicks.

 

Everyone here likes to say they can take it. But my Buddy put 3 in his 81 with cosmo 13B and no porting, and two rears. My 79 has 3rd making noise sometimes and my last 83 was having 3rd problems.

 

I broke 2 trannys with a 4 puck sprung center, 3rd gear both times. R compound tires. So its normal for me

 

Yeha you put a really high clamping clutch on the motor and wonder why the tranny breaks?

The n/A trannys are very easy to break with a modded motor. What kind of power are you putting down to warrent putting that kind of clutch on it?

 

Try a T][ or 3rd gen tranny Ryan.

 

thats very odd. I have been using a 4-puck in the RX-3 and a similar 6-puck in the FB. I have no problem with any of my trannys. In fact, the FB is still equipped iwth the original tranny, and my driving habit is not different from yours.

how about finding a REAL mechanic and stop using USED parts

 

ENGINE
13B BIG SP

Don't know how much HP but I know that the motor is TORQUEY. Im more instrested in the toqure # than HP.

As far as HP is concerned I ran 15.5 at LACR. Bald tires and Im not that good of a Drag racer, and I kept up with a SRT- 4 (14lbs) by one car length. He would only pull everytime his turbo spooled, but not by much.

Yea, I was think bout aTII but someone told me that parts are too hard to find fo that if I break it.

Will a 3rd gen tranny fit???


aint that the truth. I don't know Mel, could it have to do anything with the Master or slave cylinder the way it disengages the clutch My master does get stuck 3/4 of the way up sometimes, but SOMETIMES, and....

...yea, I always been using used parts. Only cuz i have them lying around.


oh well... I got one last spare tranny, 12a, I wanna wait to get it "geared" by Tom @ 7's only, and get that new flywheel a replace a ble friction plate, or just resurfaced.

Couple of thoughts, Im currently putting down low 15s (done mods since then, probably 14s now) on stock ports, with the stock rear end with a very similar setup. 48MM weber DCO carb. (see sig) Sounds like you got some big time tuning issues tehre man. those 4.44 gears even should amke a good difference im about to try them.

I personally dont think you are putting down the power to warrent using a turbo II tranny. I think you have been through a lot of crappy rebuilds. The only way id say you need a turbo 2 tranny is if you are boosted or are running some crazy bridgeport monster.

Again your not putting enough power down to be breaking that tranny. When the day comes that you are, id go with a TII tranny, because the FD trannys are a really differnt beast. They use a clutch setup that is really different from most cars, know as a "pull" typle clutch. all other cars are a push type clutch. Anyway ive heard conflicting reports from people who actually believe the turbo II tranny is stronger to begin with. The guy who told be this is lurking around here, and if he wants to chime in the subject hes more than welcome too **COUGH**BLAKE**COUGH** .

Id see if you can get the tranny rebuilt by someone else. Hell I just learned how to do it this week and its stupidly easy! If you access to a hydraulic press you might want to try rebuilding yourself. Just follow the shop manual exactly.

And your right it is about torque for breaking things, but we rotary people dont like to talk about that T word that we all lack

 

Ryan, it's Brad again.

Tom @ http://www.sevensonly.com/ rebuilds transmissions like no one's business. He's done one of mine, and repaired another too. He can also get you a 626 or Miata gearset in 1st gen trans case bolt in ready to go. Racing season is over so now is the perfect time to have him build you a trans.

 

Cool thanks Brad, I was just gonna call you up for his #. I need to get the friction plate and the correct counter weight cuz I dont think the one I have is correct, I need for 86-88 rotors.

Thanks again Brad.

How much does Tom charge? I think my 3rd is going...

 

for some reason, my 3rd is also beginning to make some cringing noises.. almost like grinding.

coincidence? i hope not

 

I got a good low mileage tranny. let me now if youre interested.

 

Gotta give him a call!
