Hello guys

I'd greatly appreciate any help and advice you
guys would have.

I've got a 1990 Z32 TT Auto Trans, 60K miles.

I think the Transmission just went today!

Couple days ago, it started making some strange
sound, like and extra "whirrring" noise. I figured
it was maybe a blow off valve that was stuck open,
or fan clutch stuck. . . since it made the noise
even when I revved the motor with the car in Park.

Today, driving back I completely lost drive.
The transmission just slips and I go no where,
R, D, 2, or 1, all the same.

Once I let it cool down, I can idle and get the car
moving (keeping the RPM low and not slipping the
torque converter much) and get it up to second,
and cruise for a while. Then nothing!

Anyone have any ideas what is going on?
Is it just the Torque Converter, the whole
transmission. . .

Any ideas on repair costs? Would it be possible
to just put a Manuel Transmission in it?

Other recent problems.
- The Brake Shift Lock has not worked for about 5 years
- Just 2-3 weeks ago, the car vibrates when I
accelerate lightly, at low RPM. Not when I brake,
or coast, just under light acceleration.

I've been a Race mechanic, so I have some
basic mechanic skills, but no idea on automatics,
and don't like doing any big jobs on road cars.

Thanks for any help and advice you have to offer.

Best Regards,
Vinay

the torque converter idea sounds likely to me, but there might be something else in addition to that that you might find once you get it apart. a swap to manual would be a VERY big job.

sounds like the torque converter to me.. when was the last time u changed your tranny filter and tranny oil ? some were i read there is a bolt u can be able to turn to tighten the torque converter so it wont slip.. i cant remebe were i read it... but i belive its located right in front of the tranny pan towards the engine.. if im wrong please correct me.. i have a 1993 300zx auto.. n/a/

auto's are controlled through fluid pressures and a vein system, check the level of the fluid, car has to be runing to do that btw.

second off, auto's suck. thats your biggest problem right there.

just make sure that there is fluid in it, when was the trans fluid last change?

DangerBort

Last time the transmission fluid, or filter was changed. . . I have no idea!

Could be never.

And I agree, auto's suck, so I was wondering how easy/hard it would be to swap it for a manuel. I'm guessing hard.

Anyone have any ideas on how much it should cost to get my transmission fixed?

I don't mind doing little things here and there, but this
is too big of a job for me.

I live in Phoenix, AZ, anyone live here? Or know any
good people that could work on it?

Thanks a lot for all your help.

IMHO i kinda liked the auto in my z32, you dont have to worry about burning up clutches, about your shifting and you wont get tired of it after a 1k mile road trip, but what sucks is the gearing and a lack of 5'th gear..

snwbrderphat540

ummm... and that auto's suck, weigh more, are less effiecient, and have much more to break and are more expensive to fix.

hoov100

oh please, have you ever sat for four hours in stop and go traffic with a heavy clutch? auto trannys are not less efficient it all depends on who is driving and what type of trans it is, as for the more expensive part the auto holds its own, with an auto the most you have to worry about is changing the fluid, now with a 5spd you have to worry about clutches M/S cylinders going out synchro's grinding carrier bearings over heating, and how few people still rebuild manual tranny's that and with the way technology is going today (look at the GTR's tranny and you will see what i mean) auto are going to/have surpassed the 5spd its going the way of the carburetor in the fabulous trash...U

snwbrderphat540

GT-R's trannies are much diff than a normal one. its an SMG style tranny which actually is a manual gear box, just with a new way of using it. ans as far as standard trannies go hoov, is what im talking about, they are less power efficient and usually gas efficient as well. and while manny's tend to get problems slightly more often, they are usually much easier repairs.


and as far as a 5 speed swap would go, it shouldnt be super horrible. ive done them, but not in a Z32 unfortunatly for you. usually its just the new pedal assembly cradle, new master run the plumbing add tranny shifter and finish the plumbing to the slave from the master and done, however the Z32 being MUCH more advanced than the cars i work with, i dont know weather you'll have to switch ECU's then if its just a straight swap and no REAL modifications are required, i can say though go to twinturbo.net and try to search the 5 speed swap.

hoov100

its a dam automatic it automatically selects the next gear, no physical work involved in the changine of gears (unless you have it in semiauto mode) auto are the way of the future and i welcome them, they just have gotten so dam good the past 4 years its not funny anymore, like i said its going the way of the carb....




end of story


also: show me one thing a 5spd can do that an auto cant.

snwbrderphat540

you obviously dont know how DSG and SMG trannies work then. pretty different from an auto itself and the contents inside them. and its to late to google them now. and never once did i say and auto cant do what a manual tranny cant. i said standard transmission wise in a sports car a manual is the only way to go. what are you arguing still? this isnt even what the thread is about....


edit: and if you still have more to say post it in that spammers thread you and me and bleach posted in so that we dont jack this guys thread up any more than we already did.

I changed my Volvo 740 from an Auto to a Manual, it was fairly easy (I even put in a newer year of 740 Tranny in). But 740's are plentiful in junkyards and I got to take my pick from the lot. I am going to take a guess and say there aren't alot of TT's in junkyards, especially ones that have the whole tranny and everything in it. Even then, I don't know if I'd use a junkyard tranny in my DD. Who knows what it's been through... especially if it's now in a junkyard haha.

Do some more research in it if you want to get a manual. I'm sure others have done the swap before.

KasbeKZ

manuals won't be surpassed. maybe the carburator will be, but the bulk of the people that want a sports car want a manual because of the obvious advantages that snwbrder pointed out. i can't see myself owning an automatic until i'm 50.

DangerBort

Thanks for all your helps guys.

I found one shop here that specilizes in Z's, and they basically quoted
400-600 to change the tranny. To go from Auto to Manuel, they said add about $700 in parts for the pedals, slave/master cylinder, drive shaft, clutch. . . plus buying the tranny.

The name of the shop is http://www.pitstopaz.com/

I think I'll just keep it auto, cheaper.

One advantage of having an auto, is that you do not have to worry
too much when you let other people drive it, especially girls!!
