Transmission jerks between shifts at low speed.

[CyxRyan]

2005 GP GT 122k Miles.

I've noticed this happening twice now in the past 2 days... I was on the express way both times and it was bumper to bumper for a long time. When I would stop then start to go, when it shift's it would jerk my car "between 5-10 mph". It would happen ever single time I would stop and go and accelerate very slowly. I'm no mechanic but could this be my torque converter locking up?

probably throwing the P1811 code first you need to check the fluid, if its nasty, burnt, has glitter in it, its time for a drop n fill ect. also have it scanned with a code reader and look for the P1811 - hard shifts caused by shifts taking too long (longer than .6 seconds or something)(worn clutches) which results in the pcm commanding max line pressure .... making shifts harsh/hard.. its kind of a fail safe the pcm is trying to prevent damage

Fluid was changed about 7k miles ago and before that I wasn't burnt. I also had my transmission scanned twice with 0 codes found at 2 different transmission shops. =/

After being bumper to bumper a long time implies a heated up trans, especially with no incoming air to cool it. Could be a bad pcs solenoid. You might be able to alleviate this with a tune or independent trans cooler, keeping the trans from ever reaching those high temps.

I guess a tune and trans cooler would be a good idea... I was wondering though, I know the GTP's can display trans temp on the display but on the regular ones it does not. I have hooked up a OBD and torque app to see if I can read the trans temp but nothing happened. Anyway I can make it to where it will show what my trans temp is?

Aeroforce Scan Gauge should get ya there
