need advice

[WHITE TA]

My ta has gotten extremly noisey at start up not a good noise a pretty bad tick and rattle of some sort and everytime i start it in park and with the brake on it lurches forward about six inches i dont know whats going on feels like the cars falling apart haha any sugestions on what could be wrong would be great

[MrKid]

I assume it only lurches forward AFTER you put in in drive? Maybe a torque convertor issue.

[WHITE TA]

No its in park when it lurches with the brake on

[MrKid]

Okay, is it the car actually lurching, or the engine surging? Any codes?

[WHITE TA]

Im pretty sure the whole car and a month ago i had an airbank 2 code

[MrKid]

Have you had any issues with the shifter. Indicator not lined up, detents not holding, etc?

[WHITE TA]

No it seems to be lining up right i did do a trans flush and rearend service new gaskets and fluids could i have mesed something up?

[MrKid]

Short answer...maybe. Did you have any issues before the flush? What kind of fluid did you use? Did you spray any cleaners into the valve body after you dropped the pan? Is the fluid level okay?

[WHITE TA]

I used synthetic dextron 4. The fluid level is good and i didnt put any cleaners
