I have briefly read on the transgo tug kit. Havent sat down and really read into it though.
Is it something that can be done without dropping the trans?
Truck has 243k miles. No blinking OD light bit the service engine soon light is on. Oil was thick as maple syrup and low. Trans fluid smells ok, good pink color.
It shifts extremely hard 1-2 and delayed, again quite hard 2-3 and have to let up on the pedal to get her to go timely.
I hit the OD button to get the trans to downshift to 3rd, it was everything but violent. Lol. BAM. But did go into 3rd. Doesnt seem to slip.
Does this info make you think anything? Sounds like accumulator stuff to me. But I only know what I've read. Have never worked on a trans other than filter/fluid.
