So after I did a trans rebuild, I noticed that the 3-4 and 4-5 shifts with light throttle revealed what seems to be a slow torque converter lock up. The car would shift, and then rev down to TCC lockup, resulting in a slight jolt. Monitoring the VAG seems to be consistent with this behavior.
When in 4th or 5th, letting off the throttle feels like there's a slight "let off" which can be described as a slight flutter of engine rpm up and then down through coasting.
When I run through all gears with heavy throttle, the lockup seems to be much much less noticable..it's smooth.
When letting off the throttle at 5th and slowing down, there are a couple gentle bumps from 5th to 1st, hardly noticable.
Once the TC is engaged, I don't feel any slipping at variable throttle..
I failed to pull the solenoids off and check the screens, but I did do the main pressure control valve upgrade.
What am I looking at here?
-Dirty screens at the solenoids?
-Clapped out valves/bores?
-Would the adjustment screw trick on the TCC Solenoid I've heard about help this at all?
