this morning i blew something on my rex, its drivetrain related, started on my way to work just driving normally and all of a sudden my car stops pulling and my rpms fly up, happens in every gear and there is absolutely no pull forward, dont yet know if its a clutch issue or a more serious tranny issue, axles are not turning even with the car on jackstands so...??? not good, i'll check the basic stuff first once i get home from work but figured id start asking if its a worst case scenario, What other trannies can u mate up to the zc long block without any major issues, ive currently got integra axles and would prefer not buying new ones if i do need a new tranny, i know any crx tranny will work minus the b16, any other models? that anyone knows of?

 

Any 88-91 D-series L3 will bolt up with little or no trouble.

 

Ouch, you shouldn't jack up the car and turn the axles. The cv joint works terrible at an angle like that.

 

cv joints are just fine but the tranny is toasted, as i suspected, axles spin freely and independant of each other while in any gear, if u step on the gas while having it in gear the speedometer flys up but of course the car moves nowhere. so i'm now starting the search of a new tranny, and might as well do an after market clutch and flywheel while i open it up this time. probably 2-4 weeks of downtime though, since i do my own labor in my off time.

 

it was beginning to rattle quite alot while engaging, kinda like a rear differential that wasnt balanced quite right, that was in need of new connections, kinda clunked b4 it started to pull forward and clunked when u let off the gas and it started to coast in neutral. oh well its just money and time right?....

 

You said the car doesn't go forward. Does it have reverse? Also, I'm beginning to think it's something clutch related if the car can pull forward a bit.

Well before you run off and buy another tranny, when you get your current tranny out of the car, shift into a gear and turn the input shaft and see if the output shaft turns, if not then you'll need a new tranny.

 

no there is absolutely no pull forward in any gear including reverse, if a clutch goes out normally it stops disengaging with broken cable or throwout bearings but unless it begins slipping b4 it rarely just stops holding at one instance. i'll be checking the tranny once its off the car, ive already got another l3 tranny laying in my garage but its off an hf model with horrible gear ratios im considering moving gears over and rebuilding the zc tranny if possible but i'll have to see once i get it all off the car, all of this is a good reason to add a new high performance clutch and lightenned flywheel while its open. i like the zc tranny because of the intermediary shaft which reduces torque steer so i prefer not to use an si tranny, anyone know if the gears of my hf tranny and other internal parts are swappable into the zc tranny? because i might swap over all internal parts except the lower gears and use the hf 5th gear or final gear to gain freeway drivability while im at it.

 

Oops scratch that part of about "I'm beginning to think it's something clutch related if the car can pull forward a bit."

If the problem was clutch engagement, the car wouldn't jerk forward or reverse. I'm pretty sure it is clutch related though since you can shift into gears but the car doesn't want to move. Otherwise the car would stall if your clutch was good. Hmm how does the shifting feel like? Is it sloppy? Your tranny could be stuck in neutral.

 

If the speedometer moves, the problem is most likely in the differential. The speedometer is driven off the diff.

 

But his speedometer doesn't work cuz his car doesn't move. h:
