When taking off in 1st gear with the Shifter in D4, Your relying on BOTH too hold ALL the input torque.
The Input Sprag is MUCH weaker than the Lo/Reverse Roller Clutch.
The next time the symptoms come up, Pull into D2 (This allows the Overrun Clutches too come "On" & bypass the Input Sprag), If the symptoms go away AND it's repeatable.....D2=no shutter.....D4= shutter, The Input Sprag is about too FAIL!
If the symptoms persist, Pull in down into D1, This Bypasses BOTH L/R Roller Clutch & Input Sprag, If the symptom now disappear.....The Lo/Reverse Roller Clutch has a issue.
I will give it a shot. Thanks.
I'm hoping that a new filter is what the transmission needs. I'm not going to drive it until I get a chance to replace the filter next week.
It would be great if the transmission had a drain plug (have not checked). That way I could replace half of the fluid when replacing the filter, then change the fluid again with my next oil change. And maybe a third time just for good measure.
According to Ebay there is a drain plug on the 4L60e transmission.
