b series tranny problem
Hello,
I'm having trouble with a transmission and any help would be greatly appreciated., I have a b series hydro transmission in a b16 hatch. I was told the transmission was a b16 with an LS 5th gear. He told me that he had it gone through and new carbon syhnchros put in and all. I pulled it apart just to put an LSD in and found both sides of the case to be very scrapped up. I got a clutch housing from a type r and the other half from an LS tranny, put the LSD in, measured and shimmed to the correct clearences on the diff bearings and shafts. Put the tranny together blah blah blah....,
Put the tranny in the car and started out for a drive basically. Now for the screwey part. I used an XTD ebay stage 3 clutch and flywheel. When I stop the vehicle, sit in neutral, push in the clutch, and put it in first, it grinds. If i put it in neutral and back in to first it doesn;t do it again until I left off the clutch and put it back in. I thought I had a clutch problem.,
I replaced the master and slave cylinder first. (the mast was leaking and slave was $12 buck more) This did not help.,
Thought maybe the pressure plate was weak so I pulled it out and put an OEM exedy pressure plate and put it back together, same thing.,
Pulled it again, took out the 6 puck clutch and put in the exedy disc, same problem.,
Took a sleeve and put it around the slave cylinder rod to extend it about 3/4 of an inch, no help.,
Adjusted the rod to the master cylinder in many different positions and it didn't change.,
Took the tranny out again and shimmed the clutch stud that the fork snaps on. Still having the problem.,
Any ideas to try would be greatly appreciated.,
Thanks in advanced!,
Aaron

Re: b series tranny problem
Engaging and disengaging the clutch is changing the mainshaft and countershaft speeds. That's why the behavior is different depending on what order you do things with the clutch.

Re: b series tranny problem
This one's still making me think but it ended up being a bad blocker ring, if you push the clutch pedal, shift to second then shift to first, it wont grind. Theory and reality don't always agree I guess.
