before finally engaging to lower or higher gear. All indications pointed to a tranny
problem. I took it to a tranny shop here in Toronto for a tranny service (to replace the fluid) something I had not done before and the fluid indeed was black. I drove the car some more hoping this was the problem but no luck. Took it to another
tranny shop and they connected the scanner but no codes. Long story short I took it to a GM dealership and with the scanner connected the mechanic and I took for a drive in a hilly area until the symptom occurred. We went to the shop and put it on the analyzer - the problem was the iginition - bad sparklpug cables shorting out the spark to the engine - and a couple of plugs that had been "fried". Tranny was and is still running fine. Sometimes the symptom will have you looking in the wrong place. I thought I'd share this with you. Good luck with your car.
Thanks, Zieke
Car will jerk and Tachometer quits working until car is turned off and turned back on. Usually happens when A/C or Heat have been on. Also, now this is strange, when you turn the wheel the radio volume goes down by itself...you can turn it right back up but obviously there is something wrong(and no I am not accidentally turning it down with the wheel volume controls). Just started doing this in the last 1000 miles. Electical issue??? Alternator??? Something more??? Anyone have and issues like this and maybe have what the solutions were??? If its gonna cost me a lot I am selling the thing, already put $3000 into it this past year.
I have been having a problem with my trans. and I cant seem to find anything on this problem in relation to the noise it makes. The trans. seems to be fine except for the whizzing noise it makes In Park and In nutral. with that as I drive the whizzing gets louder as the Trans. excellerates and when it shift the whizzing is less loud. The other thing I noticed is that while dirving, it seems like it shift to fast into the forth gear and so It always goes to 4th than shift right back down to 3rd. the Trans. does not slip, n'or make any clunking noise, only the loud Whizzing.
Does anyone have an Idea what could cause this and has it happend to anyone.
Thanks in advance for any help on this matter.!!
Hey I may have your solution! I have a tranny out of a 92 Grand prix that has been rebuilt by a local trans shop. I also have a brand new touque converter for it. It was suposed to be installed into my son's car but he was 17 at th time and totaled it befor I could get it put in. I've got pics I can send if you are interested. I would need a email address. I will let this go cheep...if I don't sell it soon it's going to the recyclers. My contact is mark7151mo@yahoo.com
$1,500 in transmission work and it still didn't shift right. They tried the computer program for $40 and I have not had a problem since.
miliage trany. within 5,000 miles i'll call 125,000.
1st gear no response or does not ingage
When I press on the brake the car does not want to shift out of park.The bad part is, it does it on level ground, seems to get worse when it gets colder.Is it a electrical problem or mechanical ???
Thnask, Pete
1. The transmission should not quit before 60K miles - any chance GM will reimburse for this?
2. What is the normal cost of having a transmission rebuilt? $2800 seems like alot. They do warranty it for 3 years.
3. Could it be something other than the transmission needing a total overhaul?
Thanks for any answers!!
please help
Sorry to be so long in replying.
I think I must have been one of the lucky ones. Since rob94 posted the idea of the upgrade, others have asked where to find it and it seems to be a mystery.
My car supposedly had the most current software, but the mechanic at the garage called someone in Detroit. They uploaded a new, but unreleased version on my car. Since that time, no one else on here seems to have been successful at having someone find it.
My suggestion to you is to print this stuff off and take it to a dealership. Unfortunately with the shape GM is in right now, you may not get much help.
I hope you get your problem fixed! I feel for you.
When the car warms up a little, I get a ticking noise somewhere around the trans pan/engine pan area. When I drive it goes away but when I coast down to idle the ticking starts. When in drive idle it ticks, when in neutral or park idle it ticks intermittently. :sick:
I searched the net to no avail and the folks at the local shop were clueless. Of course the Tranny/GM folks say bring it in so we can diagnose it for you... $$_^_$$ they say! Figured I'd try a few simple things before I'd let them to hack on it. Anyway today I did one major thing by replacing 1 gallon of the tranny fluid which puts me at 50% fresh fluid, definitely a noticeable difference and seems shifts fine now. The fluid I pulled was almost brown in color, versus the nice red/clear new stuff, pretty quick & cheap at $12/gal. Figured I'd do this once more but 6 quarts next time more times to get more fresh in it. I have a 1.5 gal vacuum pump which easily sucks it out in about 10minutes, then replaced it with new, I calculated that after the second flush, I'd be at 87% pure tranny fluid, if needed I’d do it once more with 6 more fresh it’ll be at 97%. Ya, I know I should drop the pan and replace the filter, but I don’t have the time and weather kind of sucks, figure I’d do it later this spring. Phase one, $12 bucks and a few minutes of my time and it seems to have done the trick. How I wish I had a :shades: manual transmission!
Hope this helps.
Thanks
Take it to the shop. Let them look it over. Warning its not cheap to fix.
I hope this helps someone out there, thanks again.
Check out message # 63, 67 and others near those in this same forum. It's all about the same issues we have and they say a PCM software update from the dealership will solve the problem for about $40! But that finding a dealership who will do it is tricky. Also they had GTs so I don't know if that matters.
I called Pontiac customer service and they were completely unhelpful. I'm taking my car to the dealership on Monday so I'll give an update if there is one to give.
My GP has been for 2 months bucking/hesitating when I'm going 45-70 mph up even a slight hill, randomly. No computer codes. I've had it tuned & the fuel system flushed but no help. Took it to a major GM dealer in Winston-Salem & they could get it to do it only once. Based on that the mechanic guesses that it's the torque converter. I went back today and asked them to update the PCM software. I was told it was up to date, they called Detroit. I looked the service manager in the eye and said, "So you are telling me that the software they installed in 1999 is the latest there is for my car?" and he answered yes. He then said that the only update is for the 97 GP (I printed message #63 & gave it to him so I think that's where he got that line). All this cost me $79. Here's what my invoice says:
called GM Tac. Case number 109*****. Advised car has latest calibration in vehicle. Calibration number is 9384244.
I have the full case # & the name of the person he talked to. I also know how customer support at large corporations works. And I feel the sm wanted to just get rid of me & my problem. I want to check this out. I have to keep this car for another 2 years. I have all the maintenance done, had the tran flushed at 58k. Except for this problem, it's a sweet ride and I'm in the car a lot for work.
Any suggestions? These guys will not lie saying the tran has been rebuilt, I know that. And I know no one in the business.
I have a 1999 Grand Prix GT. I wish you all the luck in the world in getting yours fixed. I agree about the sweet ride and great car - other than this transmission.
They updated my PCM finally after I had taken my car to the dealer 12 times (no joke) and spent $1,500. I was told by the service manager and mechanic who had worked on my car most of the 12 times that he (the mechanic) called Detroit and they put a new, unreleased version of the program on my car. I have not had a problem since.
So, there was a new version in late 06/early 07. But I wonder if it was ever officially released? Others have come on here after my posts and said that their dealerships tell them their software is up to date, but they still have problems. So, I don't think they have the same version that I now have.
Oh, and the torque converter/solenoid cost me $850 and still didn't fix the car. I actually had the solenoid changed three years prior when the car was doing the same thing for $400. Then I had to have the rear main seal fixed because they messed it up changing the solenoid. So, I've had two solenoids, a torque converter --- then the service manager decided it wasn't the transmission even though it was --- and tried a bunch of other stuff. It was the post that I printed off from here that finally got mine fixed.
I wish I could help you more. I guess my advice would be to try another dealership and see if they are more cooperative. I'm thinking that I got lucky and the mechanic got ahold of the right person when he called Detroit. If you have any other questions, feel free to ask. I'll try to help as much as I can.
