Shifting from 1st to 2nd is better but noticeable; every other shift is almost unnoticeable unless you are really paying attention.

Hopefully this problem wasn't a problem. Almost 195,000 miles now; will continue to "improve" by adding a cooler and better filtration at some point, but I don't feel any emergency at this point. Keeping my fingers crossed and knocking on wood that this keeps together until I can afford a newer, lower mileage version.


Did you ever figure out if it has the 4L80E or 4L60E? I would have assumed with the diesel that it would have the 4L80E but the hard 1-2 shift reeks of 60, not the 80.
