So I thought I'd bring my issue here to you guys!

I believe my car's TV cable is out of adjustment. I own the Helm official repair book for my car, and from the issues listed under the problem I believe my issue is my TV cable... here is the problems I've been having...

My car takes a while to be able to shift into 4th gear, I could be going miles over 40MPH until it decides to shift into 4th (OD) Also sometimes when comming to a stop the RPMs drop down almost to a stall then jump right back up every time it downshifts. I was looking through the book as to how to fix my problem and my dad seemed to think this job is over our heads. So what am I do to here? Have you guys done this job before? Am I really in over my head as I should take it to the Chevy guys? (I really don't want to have to sell my first born)

Thanks for all your help guys!

 

Probably because nobody can come up with an answer to it... just read the message over there, and I don't know why your car's doing that with 4th...

But as to the stalling out when you slow to a stop, it might be that the TCC is staying in a locked position. That's the usual sign of death for a TCC. Does this happen all the time when you come to a stop, or only when the car's warmed up? Scenario goes somethin' like this: Car's cold, runs great. Car warms up, car goes over 35 mph. Car comes to a stop- TCC doesn't disengage, and stalls the motor. (Similar to a manual-tranny'd car coming to a stop and leaving the clutch engaged.. the car stops the flywheel, stalling the motor.)

But.... tied with 4th gear... if TCC was staying engaged, you wouldn't notice that the engine's revving high lately. Are you sure it's not grabbing 4th? Maybe it -is- grabbing 4th, but the TCC isn't engaging.

 

That's how my nightmare started...every now and then, wouldn't shift into 4th....next thing I know, I'm stuck on the interstate goin 60 in 2nd gear. Would never upshift again, and smelled like burnt fluid.

Had to get another tranny. Good luck finding one like mine. I got a $300 junkyard deal in great shape, installed for 200, ran like new. That was about a year ago, and still does.

Maybe you won't need one tho. Mine didnt have any stalling out problems. You might want to get a checkup done on it anyhow.

 

i hate transmissions
i had to rebuild mine in the worst time
so honestly
transmission rebuild is the best you can do
buy a new TV cable and slap it on as well
i say instead of fixing one problem
fix all possible problems

opps i still have to put that i have a rebuilt transmisson on my sig.

Whats happening to you
happened to me
its your transmission screaming to you tell you to stop the pain..
its about to die
so rebuild or buy a new one.
even if you buy a used one
you should rebuild the used one

 

Hey Keoki, which shift kit do you have? I just ordered the $40 B&M kit (not the transpak) that includes stages 1&2, is that the one you have? What did it do for you?

 

i have the same one you have
ok here we go
i didn't feel too much on the power side
but i'm sure it freed up a few ponies

But seriously
i love it when it HARD SHIFTS!!! makes me feel like i actually have a really fast car.

well it felt better when i spanked this CRX yesterday

its worth it
takes better care of you tranny
and gives you a pony or two

i noticed big temperature diff when i got the tranny cooler by b&M

my car is cooler than before

Hope it helped

 

Camaro89dude, return that kit!! Don't even waste time opening it. I have the same kit, put it in back in '97, and then found out that all the trans rebuilders hate it. Turns out the kit causes more problems than it's worth by forcing line pressure up way too high to give the firmer shifts. Return the kit and get the TransGo kit, it's about $120 from Summit, but it won't nuke the trans. When I rebuild this trans, I'll be putting in a stock rebuild kit, and the TransGo shift kit.

Oh and for the 700r4, the B&M Transpak is just a more expensive B&M Shift Improver kit- same exact parts, but you get charged an extra $20 for a trans filter!! That's the only difference between the two B&M kits, for the 700r4. (Don't know about other trannies.)

 

TomP, I believe that could quite possibly be the problem. If I shift my car manually, 1, 2, D, OD, there are RPM changed between each gear, but when I reach OD it just doesn't drop down far enough as it should. What is this TCC you are referring to? Perhaps this could be easier to cure then I thought. Thanks.

 

i would have to disagree with u here...

just cos something is more expensive or has more
parts doesnt mean its good..i have the B&M and had it for over a year
no problems ...only extra thing i ordered was the corvette servo
and a .471 boost valve...

its true that the transgo has more parts...but trust me more the parts the more qualified ur tranny mechanic would have to be to put that in the car unless u are doing it urself ..the b&m can be put in by even the most foolish guy and still will work...(unless he is really dumb)

defnintely the transgo is better...but to get the best outta a transgo kit
its best when u put that thing in during rebuild...

the pressure problem u addressed may not be entirely true
by putting in the .471 boost valve u sort of solve that problem

 

Go do a search on the trans board, you'll see how many people, including transfixleo and ProBuiltAutomatic, two guys in the business, are against the B&M kit. Granted, I've had mine in forever (since '97), but I'm also on my 3rd trans. The kit wasn't in for the death of the original trans, but it was in for the 2nd trans. Could the kit have killed my 2nd trans? Maybe, maybe not, but the next trans I do will have the real kit, the TransGo one.

TCC = Torque Convertor Clutch. After class I'll come back and type more, but if you search the Trans forum for "TCC" or this V6 forum for "TCC", you'll find out stuff I wrote. But if your RPM's do change between manual D and manual OD, yeah, sounds like the TCC is playing tricks.

 

Here's a bit from an old message of mine, from someone saying that they thought their 4-speed automatic had a "5th gear":

So here's what you do. When you go for a drive, and manual shift, note your rpm drop between Drive and Overdrive. Then with your right foot constant on the gas, tap the brake lightly with your left. IF your tcc WAS engaged, your rpms would raise a few hundred. If your TCC isn't engaged, engine rpm will stay the same. Remember you want to touch the brake enough to turn the brake lights on, not to slow the car.

And if your defroster clicks on with your brake light, check to make sure none of the metal wires on the hatch window have fallen onto the hatch lift struts. But I think this is just an '86 thing (solder releases the wire for the brake lights from the window, the wire lays on the metal strut piston, when you tap the brakes, the defroster comes on because the strut piston is the source wire for the defroster). Reason I say this is because if you're putting your defroster on, the circuit would cross over onto the brake lights, and disengage your TCC.

Ever hear those new Aamco Transmission radio ads? "Your engine is revving high, and your brake light bulb is burnt out. Could this be a serious transmission problem? Bring it to the experts at Aamco, who can tell if the problem is transmission related or otherwise." With this ad, they're talking about the brake light de-activating the TCC solenoid.

 

i have a little info that may help.

When i bought my 91 bird, everything was fine and dandy until one day i was under the dash checking things. I noticed a switch with push button on the end of it. It was supposed to be pushed in a plate so my brake pedal could de-activate the switch when i pressed the brakes. So after i hooked it up, all of the sudden my trans felt funny.

Turns out that switch ran my TC, the TC would not lock up because it thought i was always on the brakes. When you hit the brakes it unlocks via that switch, maybe that switch is just hanging there not doing anything?

I know that was my problem


p.s the trans only felt funny cause i had never felt the TC lock up, i had always driven a stick until now.

 

9D1, there's two switches? I thought the TCC ran off the brake light switch. Hey, that's great! My TCC's been acting up, I noticed if I put my foot under the brake pedal and lifted up, the TCC would engage. I figured I had to replace the brake light switch... never looked to see if there was a separate one. Great, thanks!!
