I'm doing a B18C swap, with LSD transmission in my DA. The motor is NOT in the car yet, so this is why I'm asking now, instead of later. I will be using the Innovative Cable-to-Hydro conversion kit (the mechanical kit, not the full hydraulic conversion) and I have encountered what seems like it could be a major issue. To be clear, this is a hydraulic transmission, being used in a cable transmission car.

not sure what it's called, (release fork, maybe?) but the lever that operates the clutch on the transmission (that protrudes out of the case) is doing something weird. When I removed the hydraulic setup, I checked the play on the lever, and when I push the lever back (as if I was depressing the clutch), it goes back fine, but doesn't automatically retract back to the original position. Is this normal? I'd hate to be driving, push in the clutch, and when I let the clutch out, the clutch not engage due to the lever not coming back to its natural "resting" position.
Make sense? is this normal because the car isn't under load or being driven? or is it faulty?

 

I'm surprised you can push it back by hand... are you sure it's not popped off of the ball internally? If it's correctly pivoting on the ball, perhaps there's been some rust or crud that's fouled the splines; tho, hard to imagine a healthy clutch not having the strength left to push almost anything back.

I'd suspect the clutch..

 

I have been doing some research on the subject, and read a lot of articles stating the the cable clutch in my LS transmission is interchangeable with the hydraulic clutch in the GS-R.

my car is a 92, so it has the same size shaft and amount of teeth on the spline. So, to confirm, it IS interchangeable, right? since mine is a 92 that has the same shaft size and teeth count. now the next question, is what lever will I need to use? the hydraulic lever (I have the Innovative cable to hydro kit), or will I be able to re-use the cable lever from the LS transmission? if I can use the cable's original lever, then I'm sending the Innovative kit back for my $150 refund.

is this right?

 

Sounds like a bad clutch slave cylinder.

 

Slave cylinder is NOT on the transmission. It was removed so I could use the Innovative Cable-to-Hydro kit. My DA is not hydraulic. It's cable.

 

I see. Then in that case, nevermind. My car is hydro so I wouldn't know. Good luck.


I would do a full conversion, I've read some mixed opinions about these kits and how they aren't very reliable in the long run.

 

Are the motor and tranny bolted together? If the motor is off the tranny then its not going to slide back

 

hey guys. My dad came out to check on it today, and he informed me of something I didn't know about hydro transmissions. that the fork has play in it to begin with. he suggested using a pry bar to see if the lever went back any more. I was able to muscle it about another 2.5", and it did return to its original resting position. my hydraulic transmission noob level is showing

sorry, lol. I've only ever owned and worked on cable transmission cars.

clutch = fine.

/thread.

 

Excellent outcome! Nothing quite like eyes on, is there? ; ' ) Go Dad.
