Angry What is Bump Shift? Do I have it??

Please read all .... there may be some details in here.

Details: 95 Dodge Intrepid 3.3Liter 85,000 Miles. All Service done by Dealer.

Symptoms: Car seems to hestitate when getting up to speed 0 to 40 MPH. At 40 MPH the car starts to Jerk, Bump, Hestitate. I give it gas...seems ok, But if I try to level off anywhere between 40 to 60MPH the Jerk/Bump/Hestation Returns.

History:
1st Battery replaced (the above did not occur before battery replaced)
2nd Symptoms above arrive...in dealer for 2 days, can't find problem, thinks its ignition coil, ok repair, charge $276 for Ignition Coil and spark plugs regapped (fuel fouled??).
3rd Still have problem take back to dealer. Mention fuel rail because cousin had problem in their '93 with the fuel rail. They say fuel rail ok but all 6 Fuel Injectors bad. OK replacement of all 6 Fuel Injectors. They have car for 11 days Charged $606
Still have problem!!
4th Service Manager calls and says that he still thinks its a fuel issue not a TCM issue. That if a TCM issue will cost around $700. They are willing to look at it again by dropping the tank, cleaning fuel lines, fuel pump and replace fuel filter. No Charge (they are so nice) sarcastic.

Still have Problem.

In talking to the Techs before talking to Service Manager they said they cannot Flash/Update my version of the TCM. He also said they cannot replace it. In talking to Service Manager he does not say they cannot replace but that TCM Service would cost almost $700 and they want to make sure its not a fuel problem 1st...evidently not a fuel problem.

My Questions:

Is this the infamous bump shift?
Is my TCM Flash/Upgradable (they say its a 1st Gen??)?
Cost of TSM Replace and complete Trans Fluid and Filter replace?
Is there a TSB on this, which one, could someone send me the TSB?

I am far from an engine expert but I kind of doubt if it is the TCM. Not aware of the bump shift issue you describe...maybe one of the first gen guys can help you out with some info.

Sounds like this dealership is doing a lot of guessing and in the mean time it is costing you a lot of money. Might think about taking it somewhere else. With the money you have spent so far you are almost to the point where you should have just totalled the car and looked for a new one.

From what I recall and have (still have to get it fixed) bump shift is when you are coming to a stop and you physically feel a hard downshift or bump into neutral. It can also be somewhat delayed causing hesitation in acceleration from a stop. Bump shift, I believe, does not have to do with shifting at higher speeds. Also, if you have ever been in a 1st or 2nd gen dodge minivan, you can feel the same downshift as in these trannys. That is what I believe we call the "bump shift"

Bump shift is when you are in an orgy and someone yells "SHIFT!"

Yep. ;)

Btw Rosko, if what you're describing is converter clutch shudder, then that's usually symptoms of an incorrect tranny fluid level or type.

Any chance someone may have put the wrong type of tranny fluid in your car?
