Buick Terenza transmission issues? Sign In

Hi everyone I'm new here so hello. I'm looking for some advice on my 06 Buick Ternza 3.5 260000 mi. I'm having a transmission issues I'm pretty sure. When it warms up and come to a stop it bucks and jerks until it get up to speed. I want to believe its a wheel speed sensor since the abs and trac light are on. No other codes except egr insufficient. It was two and a half qt low on fluid so I topped that off. Hopefully its not a pressure solenoid since I think that would throw a p1811 code. Thanks in advance for any advice.

Our trans expert Gary will be along but you first need to get the ABS codes read. You can't use a simple generic code reader. You need a scan tool capable of reading ABS.

Post the "C" code numbers here.

Hello,
P1811 is max adapt and long shift, can be caused by EPC solenoid can also be caused by the clutch packs simply being worn out, if this was low on fluid i would certainly fill it, you may have to reset shift adapts to see what happens, you have a harsh 1-2 shift sometimes? Gary

The way I understood him I don't think he actually has that code unless he left some words out.
