Went to scan my car today and i got this code P0702 witch means transaxle actuator lost power. What is a transaxle actuator and what does it do? also what can be causing this problem?

also my interior lights pulse could it be related?

Think it's something to do with the transmission, not positive.

An A4 I'm assuming?

Is it shifting ok?

Googled from a Saturn site (I assume to be similair since they're GM):

"The transaxle is a fully automatic unit consisting of four multiple disc clutches, a four element torque converter with a lock up clutch, 1st gear sprag clutch, and a servo actuated dog clutch.

The most significant departure from the traditional automatic transaxle comes from the use of electronic controls. This unit utilizes five electrohydraulic actuators in conjunction with a powertrain control module (PCM) and its sensors to control shift timing, shift feel and provide on-board diagnostics.

The transaxle control actuators are electrohydraulic solenoid valves consisting of a housing, valve body, sliding armature and electromagnetic coil.

The actuators are located in the transaxle valve body."

I assume time, faulty parts, used fluid, etc is the likely cause of this.

As far as fix for this, I am no transmission expert, so I got no help.

well is a M-6 car still drives good and shift's good, the only thing is wen i shift and the rpm's are like at 15k the car kinda bucks like if im not giving enough throttle and sometimes wen im like in 3rd around 2k rpm's and i let of the gas it engine breaks really hard but then it stops and goes back to normal.
