Help!!!

[SarahMarie]

I need help, I got my 91 3000gt sl auto about a year ago, for the first few weeks it ran great, then when I was driveing to my fiance's house the engine jumped, reved, and made me feel like I was going to be thrown out the window. It does it more when your off the gas. Well, since then, in a year, I've had the doors rewired, (the alarm keep going off), had a 45 cent bolt replaced when my gear shift decided to die and had to be towed home .2 miles away, (that was a nice bill)... I've had the engine mount replaced or fixed, had the end cluch replaced when my overdive went out, had my motor on my window replaced when it stopped working, had two of my struts replace, had the recall done, had all the plugs replaced, and had my brake pad tightened. And still, my ac has stopped working right, the car still jumps, you can be driving down the highway and all of a sudden don't have power from with the gas anymore,(you have to stop and turn the car off for a few minutes and it will start working again), and just started to "not go in gear", we were at the drive though and put in it park, went to go, and put it in drive and the engine just reved. And it has done that more then once. The one thing I havn't done is check the ECU.

Now, I don't know what to do, take the money and get a new tranny and everything? Or, take the money and get a new car that might have problems with it... What should I do? (Any Ideas what may be wrong besides the tranny? )

Thanks for any help.

I had the same kind of thing happen to me and you might want to have your differential checked out. The gear could be worn and are slipping. With the shifter problem you might want to check the shifter cable because i worked on a car where all it need was a new cable to make the car shift perfectly.

I hope that this gives you some new ideas.

good luck

Hmm... I'll try that, thanks. ^^

Since you haven't checked your ECU yet, go ahead and check your ECU for leaking capacitors.

Ok, now, I started "going into neutral" while I was driving to work (that was fun... ) I came home and went to check the fluid, it was fine, but I noticed that there was a "weed wackier" like sound coming from my engine, could what was mentioned still be the problem? Or is it likely my tranny? Help?

You getting a check engine light? Have you checked your ECU caps? Weed wacker sound could just be an exhaust leak....impossible for us to tell without hearing it.

With all that is going wrong I would really assume the ECU or the TCU would be throwing codes.

Thanks. I guess, I could have explained it a little better..lol No engine light, and my finance said it sounded like friction, It's coming from my engine, maybe left side? It happens in neutral, in reverse, and in drive (sometimes)... To me it kind of sounds like gears grinding... Also, when I turn the car on and take it from park to drive, my foot still on the brake, the engine revs a little, pauses, the lights dim and then it goes into drive... I really hope it's my ECU... I love my car.

Also, this is all with the overdrive off, i havn't checked if it happnes with it on yet... If they didn't install my endcluch right, it wouldn't happen with the over drive off, would it?

[SarahMarie]

Oh, it also almost dies going from park to drive, or reverse... The lights dim, engine quiets, then it goes into the gear...




(I'm going to try to check my ECU this week, i just want to know if this COULD ALL be from a bad ECU... )

I just took my ECU out, and it IS leaking a little from the 16V capactior, now, do I buy a new one, or, send it in and have AVpro repair it?

You can send it in, however if you know someone who is pretty good at soldering components on circuit boards then you could have him/her do it. Doesn't take very long if you have a good soldering iron, bench vise, and a solder sucker.

That sounds like the tranny. When my tranny went out it had those exact symptoms like when it kills putting it into drive or reverse along with the weird noises. If I were you, I would take it to a trustworthy transmission mechanic just for a diagnosis. Hope everything works out ok.

Yeah, I talked to the guy at AZPro and he said that it wasn't from my ECU or TCU. I think thats what I'm going to do, I found a cerified transmission repair shop here in Colorado, the will do a free diagnostic and I will go from there, I am going to send in my ECU though, since it is leaking. Thanks for the imput, it's comforting to know someone had the same problem as I'm having, I was just afraid that's not all that's wrong with it... still am a little... Thanks. ^^

Definitely sounds like a tranny problem. I'm not sure how many miles are on your car, but I would bet the clutches are finally wearing out of material. It sounds like rebuild or replace time.

or MTX swap time!

right, the tranny problems wouldn't result from a faulty ECU, however, if the capacitors are leaking, they would still need to be replaced anyways.
