I treid to put my car into get this weekend, and when the engine is running I cannot put it into any gear, but with it off it shifts into gear correctly. Its a brand new transmission, and its a 93 M6 bolted to a 95 engine.

I think I may have hooked it up wrong, does anybody have a clue?

Thanks,
Kevin

 

what do you mean by you cant shift?
it grinds in?
shifter is "locked?"
it wont stay in gear?
clutch slips?

 

Sounds more like your clutch isn't letting go rather than a transmission problem.

many times a faulty slave/master cylinder will cause the car to not shift into gear while its running but it will go into gear while the vehicle is off.

 

Hello, thanks for the reply's, I have a brand new clutch master/slave cyclinder, new flywheel, clutch and pressure plate and the tranny is freshly rebuilt.

I am thinking that I might have hooked up the electical plugs wrong, do you think this is possibility?

Thanks,
Kevin

 

it(obviously) had nothing to do with the electrical connectors. it DOES have something to do with the clutch/master/slave. the clutch is not completely disengaging. what clutch is it?

 

Its a SLP Lightweight Flywheel, SLP Pressure plate and SLP Clutch, I also have all new GM clutch fork and GM Clutch master/slave cyclinder & related parts. The Tranny was rebuilt just before it was installed.

I apologize for my ignorance, but I don't know much about the T56 tranny, and when I hooked up a JET CAGS elimanitor before I had the tranny rebuilt I had the same problem since my tranny is a 93 without CAGS and the engine is a 95 with the CAGS provision I was unsure.


Thanks everyone for you help, I appricate it.

I had a similar problem and it sort of fixed itself. I worked the pedal about 50 times and then, with the car on jackstands and running, I put it into gear and let the clutch out. I repeated several times and it started working properly. I just needed to acquaint the pressure plate and flywheel more closely with the clutch disk.

 

I think I found the problem, it seems that the clutch fork is slipping on the TOB, I got it in engage last night while it was running and on jack stands (not the smartest thing to do.. I know), once I dropped it back down, I guess it came loose again cause now it won't shift.

Any thoughts? Can you remove the clutch fork without removing the tranny?


Thanks guys,
Kevin

 

No.

I'm with the other guys though...sounds like a slave/master cylinder issue. Just because it's new doesn't mean it's good. You also might have to bleed the air out of the fluid. The Fork is supposed to have some play in it on the bearing, quite alot actually. It should firm right up when you install the slave.

 

Whats the procedure to bleed the master/slave cyclinder? Is there any way to test to see if the M/S Cyclinder is good?

Thanks,
Kevin

 

Yes you can have the plugs hooked up incorrectly and cause it to not shift into gear. I installed a 94+ 6 spd in my 93 and have accidentally hooked up the plugs in the wrong spot. Both times I could not shift into any gear with the car running. I could with it off though. I am at work now and cant get specifics, but it is something to look at.

Do you have a 95 wire harness or a 93?

 

I dont think I will be able to help a whole lot because I dont have a wire diagram for the 94+ with skip shift. However, I do think your problem is because you have a 95 harness and a 93 trans. The 93 tranny does not have the skip shift solenoid in it, but the computer is looking for that input through the 95 harness. What did you do with that connector?

 

I hooked up a jet cags skipshift elim. on it. Do you think that will work?

Thx,
Kevin

 

I would think that would work.

The 2 connectors I had swapped on my tranny were the 2 aft most ones on each side. One is the backup switch on the passenger side and the other is the lockout solenoid on the driverside. The easiest way to explain is that one was on one side and the other was on the opposite side.
