thanks mark
the ET designation makes this a euro model but its the same as the AT. What i'm sending you will show metric and US standards in the tables so you should be fine with this.

hey mark, the site automatically removes weblinks and email addy's out of posts. You can alter the email address by spelling it out like youremail dot com or you can also go into your profile and adding it into your signature, it should work that way also.

I had a unit last year with the same problem

Pressure tests in PSI

Main 142.2 to 177.8
Clutch 142.2 to 177.8
Torque 14.2 to 71.1
Lube 7.11 to 72.7

Test run at 1600 RPM

We found low clutch pressure, pull trans apart and found broken Snap rings on the Fwd/Rev Clutch packs. Hope this helps.
