Ok, I got a master question for you. My car drives perfectly fine in drive however, when I put it in reverse and get to 1000 rpms it jolts to 30 mph backwards. I have been told it was the transmission so I took it to a transmission specialist and they said it wasent the transmission and they refused to work on my car. Then I took it to another macanic and they told me it could be electical or it could be the computer so I took it to another macanic and they looked at it and they said the same about the electrical and the computer. So, I took my computer ourt and sent it into a company that tests computers and they said there was nothing wrong with it and sent it back. Then I talked to the dodge dealership and they said I could bring it in and they would charge me $105 and would do a complete diagnostics but if they couldnt find anything the wold charge me again and do it again. Then I have talked to about 10 other macanics and they have never heard of it and are not willing to help so it leads me to you. Any Ideas?

I will try to handle this question with my 2 cents, but I will not charge a penny.
You put it in reverse, and you have an overdrive transaxle with a 3.3 or 3.5 L.
As you back up, what do you feel from the accelerator pedal, and has anyone test drove this vehicle, and has anyone(even Autozone) read codes from trans or ENGINE?
Is it as if the speed control is taking hold and controlling your car, or is it just the speedometer that goes up. This I will tell you. If you answer my questions, and you take your time, we will, without any doubt, find out what is wrong and I am sure this is not a master problem. I can't drive it but I'll do my best. Since 93, almost 85% of my work was with diagnostics on Chrysler electronic and hydraulic problems. And so many were Intrepids. Ok No matter what, the transmission can or cannot cause this, but if you help me with answers, I will help you with answers.

My car is a 3.5L and my pedal gets pulled from my foot all the way to the floor board and yes I have had about 3 machanics my dad, and my uncle witch have soon experience with cars and its the same for them and yes I had my family macanic test it for codes and nothing came up and then the transmission specialist also tested it for codes and nothing. And yes it does feel like the speed control takes over ooooo and sorry about that thats also one thing that one of the macanics said so I had took the speed control accelerater cable off and it didnt change and I really appreciate your help and I really thank you for your time.

Good day, since I read your first post, I have been thinking, and contemplating the way that I could help, this is my way of asking for this problem to occur to me, and help, in some way for you to solve your cars overly powered reverse situation. Sure enough, my contemplations have been answered, not in a 3.5L Intrepid, but close, We used to call it, "close enough for rock'n' roll". I started this car, it was damp, cold, colder than other days so far this year. Since reverse is the usual gear a car is used for backing up out of a driveway or space first thing in the morning I noticed the gas pedal and car taking off on its own. With my car I liked it, only because of my particular legs. But my older friend didn'y and I'm sure no one else would either. That was my purpose for becoming an auto technician. Although my friend took out his Intrepid and knew nothing about the eventual accelerator problem, a new car, and a mans life were lost, since even 200lbs of pressure on the brakes could not stop this car. Normally, a problem like this would not have been so bad, and the problem would be found eventually. Then the manufacturer would re-imburse the dealership, who then would re-imburse the technician for replacing the part that failed. However no one would re-imburse the time any technician, mechanic, or human being would spend to find out what was wrong. Anytime any problems occur, that in anyway put a human life in jepeordy, the keys would be in my pocket. I could care less, if this car had to sit for 5 weeks or 5 years. I was not a 'race fan'.
Today it was a cold related problem with the throttle blade and its relationship with the bore it was designed to move smoothly in, as speed increases so does vacuum and as the vacuum matches the power, air prssure actually was pushing the throttle blade. With a TPS sensor, and IAC motor all involved, many people are fooled. And the codes can be decieving. In my case, It was a simple dirt, temperature, and a few squirts of cleaner, some lubrication and some brushing was all it took. The throttle blade, and mechanisms were sticking. But if this car belonged ta any customer, the therottle body was replaced. Not with a reman, used, special type, or performance throttle body. A Mopar new throttle body was used. And fortunastely for everyone, the car or truck was finished, and Chrysler would pay for installing a new one as long as it was covered under the warranty. Glad for the 48 minutes, pay, but at least no ones life or future was changed for years to come. Any help this may have been to anyone is greatly appreciated by me. Please do not let anything safety related happen to you, if your throttle body, the component that controls the powerr to a 6 clylinder power plant, in your case, is even slightly suspect to be bad, replace it, all of the sensors also, then take it for a good long ride to make sure it is ok. Being careful, and driving it in a place where no one could be hurt, especially you. These days, money is placed in the way of human life. No Good in 1939, 1914, and no good in any one life, at anytime. Have a good life. A lot of techniciasns, mechanics, people and yourself, are giving their lives so others can live better. Hey, you gotta do, what you gotta do. OK thank-you.
