2006 pontiac grand prix transmission problem?

60

Asked by rdengil1 Jan 13, 2014 at 09:08 PM about the 2006 Pontiac Grand Prix

Question type: Maintenance & Repair

I left to go to dinner tonight and my grand prix ran fine.  Got to the first stoplight in the neighborhood and when the light turned green the car ground a little and then jerked forward, then next light a few hundred yards away, it would not go forward in drive, or drive 3, had to put it in drive 2, once I got to about 30 mph, I put it back  in drive and hit the highway, was fine.  But every light I hit it did the same thing.  Temp of trans fluid reached 221.  Not sure, why it did what it did, but why would it not drive in either drive or d3, but work in d2, d1?  Again, once up to normal driving speed I could put it in drive and as long as I don't accelerate quickly, it will be fine.

Also, there is fluid at the proper level, car has about 108K. Could it be clogged filter or time to change fluid completely?

Torque converter is staying locked in. This sets in the front of the transmission.

You can try changing the fluid but I would say it needs a torque converter. Add a quart of lucas transmission treatment when you change filter and fluid .If this doesn't help it you need a torque.

Chances are your transmission is already finished, but the sooner you get it into a reputable shop and get it looked at the better your chances are that it might be able to be repaired and saved.

Boost valve plays a big part in these trans. I replaced mine like a new trans. When you get that done might as well replace cylinoids

These cars are notorious for blowing through transmissions I had two Rebuilds on the one I had. Loved the car hated the transmission
