With the 7.3L's 4R100 transmission what is the main failure those of you had fail?
The 2-3 gear shift seems very very sloshy and extended at least with our truck depending on acceleration pressure which seems to be the failure point but wanted to hear from others.
We do have a new trans in the plan.
On edit Sonnax and Tricumulator was installed a couple years ago which helped 1-2 and 3-4 shifts which both still remain firm.
