I have a 06 Pontiac Grand Prix it has 128,000miles i just had a rebuilt transmission put in it. But now when driving the car for about a hour when the car gets really good and hot. Its like the transmission is slipping. I took it back to the shop that put in the transmission and they said it`s` the C.Converter i took it to a muffler shop they did a back test on it and said it`s fine.(the converter that is) It makes my Traction Control light comes on. and it`s like the car does really wanna go. To me it really feels like the transmission is slipping cause it jumps alittle. but sometimes when you push the gas paddle it`s like the car wants to take off.The rpm hand jumps up a little every now and then when the car is messing up. But if i park it overnight or for a few hours and let it cool off. and go back and drive again it`s fine.. until it gets really hot again. The check engine light isn`t on. So what is wrong with it?’.

  1. Well, It is either the transmission, or the plugged catalytic converter.

  2. Plugged catalyic converter? What does that mean?

  3. Plugged, clogged, poor flow, etc
