I am currently running a 100hp tune from Steve at ssdiesel and have had no problems at all. Trans shifts quick at low or full throttle. A few weeks ago I get in the truck and it shifted fine into gear and no slipping taking off but there is a pause between gears 1-2, 2-3 and 3-4 of about a second or so. Turned the tune down to tow and no problems. I have around 3500 miles on a transgo jr and new spin on filter. Did use Supertech Dexron VI on the refill as I was assured that Dexron VI is Dexron VI. I really don't want to put the $$ into a full trans rebuild at this time if I can help it.
Any ideas?
