I took my Vette out for a spin tonite and everything was fine when I was doing errands. However on the way back home as I was driving, I tried to speed up but for some reason the Vette is hestitating and the rpm guage was showing it was going over 3200 and it seemed it was stuck in a gear or something locked up.
Now the way I normally drive is that I keep the car in Drive and when I get over 55 mph I tend to put it in Overdrive. The battery came on as well which I didn't understand.
I do know that I havent changed the u joints on the drive shaft yet. I only did the half shafts. Could this be an issue with the u joints or is it something with the tranny ?
As for one more thing.. the coolant temp was reading 200 to 201 when driving and yet when I parked the vette in the garage and shut her down, I could hear the headers crackling. I'm getting a little worried here that I may have serious tranny problems.
Thanks for yoru help in advance.

 

Me too. Except, I'm more then "a little worried". It is not the u joints and the batt light (?) is unrelated. Good luck, and...

RACE ON!!!

It was sticking in 3rd as you put her in OD? Or was it sticking in 2nd?

Sounds like it might be rebuild time if its not something with the cables sticking or linkage, the battery light should be unrelated.

 

Whens the last time ya had the trans fluid/filter changed and all trans linkage/cable readjusted?

Is this a 4+3 or automatic?

 

sounds like bad news.my 84 had 99000 miles when it went.it did the same thing as you discribe as your car is doing,stuck and wont shift.but it could be something as simple as a bad connection.you didnt say how many miles.good luck.

 

"the rpm guage was showing it was going over 3200 and it seemed it was stuck in a gear or something locked up. "

How much over 3200 was it going?
Will the motor rev in neutral? If not then it's not the driveline.
Although your description is a bit ordinary , I had a similar effect when the cats blocked up.Would run fine until around the 3000 mark then flat spot. Change gear and the same would happen. Motor ran hot.

 

It's an automatic and if I speed up slowly or gradually then it shifts fine but when I punch it it seems to be stuck in 3rd gear. I changed the tranny fluid and filter about a year ago and it still looks a little red. I havent driven the Vette much since summer and even before then there were no symptoms or anything to make me concerned.

 

I would try adjusting the TV cable and greasing/adjusting the linkage before doing anything.

What you described here happened to me once after I had my seals replaced, and it was just the TV adjustment. It had a slight kink in it.

 

How would I go about doing that. I never done this before. Thanks.

 

check the "tools" 'tech tips' - theres a procedure there for adjustment :thumbs:

 

Well I did a little research at http://tvmadeez.com and i came across a statement made about adjusting the tv.... one extremely important point needs to be made. You may notice that throughout this article, the term "adjusting" the TV cable will carefully avoided. We will do this for a very specific reason. We have read lots of General Motors manuals explaining how to "adjust" the factory TV cable. While most GM publications used the term "adjust", when you actually followed their procedure, what you actually accomplished was to "set" the system to its correct W.O.T. position which will in turn automatically "set" the correct starting position. This Part One will explain this in specific detail. We are not aware of a single GM publication that advocates "adjusting" the TV cable once it has been properly "set". We are not being "****" about semantics here but commenting on the wide spread belief that the TV cable system can be "adjusted" to make the transmission "act" better. As far as we know, this system was never designed nor intended to be a transmission behavior adjuster. We further feel this is a very dangerous practice being performed by many "professional" transmission shops and mechnanics. Once have read the remainder of Part One, Part Two and Part Three, we believe you will agree with us that once a correct TV relationship is "set", you cannot re-adjust it without creating a problem of some type.
Now tell me if I'm misunderstanding something here but it seems to me that its not good to adjust the TV whereas it will cause more problems down the road ?

 

I'm kinda with rodj on this one. Have your cat checked. If the car is shifting "normally" until you get on it that is similar to symptoms I was having when my cat was plugged. Some muffler shops I've heard have a way to test them, but I just removed mine and gutted it :smash: All better, till I blew it up :lol:

 

Well I had my Y pipe and cats replaced about 3 years ago. The car isn't heating up though, I just think it may now be the TV cable needs adjustment since it wont shift out of 3rd gear in WOT. If I drive to accelerate slowly then it shifts fine. Otherwise when I floor it it won't shift out of 3rd.

 

I'm going to guess you have a little governor trouble. Could be a little piece of 'stuff' got caught in the valve of your governor.
Any shop can remove the governor and clean it or you can do it yourself.
It's a good place to start.

The TV cable sets the 'operating pressure point' of the transmisson.
The governor works in conjunction with this pressure to determine the shift points.
That's why 'adjusting' the TV cable will affect the shift points AND the shift 'feel' to a small degree.

 

How much do you think it will cost to have the governor cleaned and the Tv cable adjusted ? I'm not worried about the labor charge though. I'll figure it out when I decide which shop to take it to. I'm afraid to do anything relating to the tranny for fear of ruining it. I had a tranny replacement in my Camaro awhile back and hate to have to go through the costly repairs again. Thanks.

 

yea sounds like your trans is slipping...

Setting the TV cable takes about 3 minutes. A reputable shop will likely do that for you free.

Take a screwdriverand release the lock out at the TB and slide the cable ALL THE WAY BACK.
Get in the car (don't start engine) and press the gas pedal ALL THE WAY to the floor.
The TV cable is now adjusted. Nuttin to it. Anyone can do it, one person job.

Removing and cleaning the governor will take about 30 minutes.
That's whatever the shop rate is for a half hour. Probably 40 - 50 bux.

A good shop will connect a pressure gauge to the test port on the transmission and run a series of pressure test and diagnose that tranny for you for a modest fee. It doesn't take long to test it properly.

Shops wanting a lot of bux for the above mentioned procedures are just out to rip you off.
Take your car somewhere else until you find somebody that is willing to work for a living.

You can pull that governor yourself. It's a no brainer.
Got a cover over it you pry off. The governor just slips out.
Not much fluid will come out because the governor is above the fluid level in the pan. Wash it good in the sink with hot soapy water. Be sure to move the little weights back and forth to get the fluid passages clean.

Pulling the pan on it and changing the filter is another thing you can do.
It's a messy job though. Old transmission fluid will get all over you and everything near you. NASTY job.
Filter slips right off but there is a seal that usually sticks in the filter pickup tube housing hole. You need to use a screwdriver and remove it before installing the new filter.
If the fluid in your transmission is nice and clean and red then you may consider changing the fluid and filter.
If the fluid hasn't been changed in a long time/ lot's of miles, don't change it.

There are several "check *****" in the valve body assembly and sometimes one will stick open or closed and not allow the pressure to be correct causing odd problems.

If all else fails the tranny may at the end of it's useful life.
It could have clutch packs/band wear beyond serviceable limits.
A rebuild may be the only answer in that case.

Good luck with it.

 

Thanks for the info.. I'll take a look at it when the weather warms up a little bit. It's going into the low 12's tonite and its windy. Plus the garage is gonna be like an icebox! Its great to be able to come to the forum with questions and concerns. Thanks again and I'll let everyone know how it turns out. :cheers:
