I have followed that process, but the strange things is that it´s not slipping in D (if engaging kickdown on 2500rpm it slips and goes to redline, 2100rpm kickdown is fine).

Some feedback..

Teared down the Valve Body and dissasembled it fully to see if there was any blockage and also test all of the solenoids. I didn´t remove all the pistons but checked that they moved. What I saw was that piston B1 accumulator was rather worn full of scratches (don´t now if that could be the problem) part nr 3542460030.

I can drive the car forward, but it sleeps when i do kickdown on higher gears. It engage reverse.. but doesnt have the strenght to move forward..
Haven´t had the possibility to test the hydraulic line pressure yet.
I have a error code P0894.

I have no warranty.. so it looks like i´m aiming for a new transmission

Any ideas are most welcome.

just checking on that process. your sure the trans temp fluid was at the right temp before you drained the over flow drain plug right? i believe the temp range is between 115-133 deg F. and that you let it come to a drip before closing it off. Im not quite sure which year it is but there is a couple that the manufacturer messed up on the level design and now have a TSB and special service tool to get the level right. be short or over even 1/2 a quart can cause issues.
