190E transmissin - no forward gears
 

I have a pretty helthy 1988 190E 2.3. (147 k miles) except for a little detail: The Aut transmission only work in reverse gear. Shifting to other gears gives no reaction. I have diagnosed this symptom in 'Alldatadiy' to be:

'Damage to B2 piston T-form ring resulting in total leakage of Band 2 application pressure' and the remedy is to replase the B2 piston T-form ring.

I can se from exploded view that the B2 piston is kept in plase by a metal bar secured by screws in the valve body. My questions is:

Is it that simple? How do I access the valve and how do I perform the T-form ring change?

I need specialists here! please help!

Best regards

Almost all of the time that that style trans won't go forward, the B2 band(or piston) is broken. You lower the trans support & depress the piston to remove snap ring, cover, & piston. Good luck!
