a. Being a Turbo, you are putting more Torque on the Transmission that was initially designed and it might be wearing out b. Motor Mount and Transmission Mounts might be worn out or broke.
My Gut is telling me that your Mounts are BAD / BROKE and need to be changed. 3rd has more torque than 4th.
Try this... Find a Friend to do this with you: Raise your Hood Put your PARKING BRAKE ON.... Stand on the PASSENGER SIDE of the Van Have Him/Her Start your Car Have them put their LEFT FOOT on the BRAKE PEDAL Have them put their RIGHT FOOT on the GAS PEDAL SHIFT TO DRIVE and GIVE IT GAS and watch and see if the Motor turns. SHIFT TO REVERSE and GIVE IT GAS and watch and see if the MOTOR TURN (It will go the other way... TORQUE
If the Motor Raises up more than 1-2 inches, it is a Motor Mount
Ok what your describing is your Transmission not shifting between gears so low or no transmission oil means a slow car and at risk at damaging it so ckeck the oil level and if you have got full oil it it then you will need to take it to a mechanic.
sounds like a trans mount when they go bad it causes all kinds of shakes , have someone put in gear ,open hood,, watch motor. tell them to hold brake and give it a little gas .Don;t stand in front of car .....see if motor raises up if so replace all mounts motor included. this is a common fix on theses cars.
There is a pressure sol. in the transmission that is bad . This is a common problem that requires removal of the side transmission cover. The transmission does not need to be rebuilt! Talk to a gm dealer. I have sold over a hundred of these pressure sol. and the side cover gaskets to a real gm transmission mechanic that have fixed this problem. GM parts over 20 years.
