Default 4L60e acting a lil' funny

My WOT 1-2 shifts seems to be really slow and drawn out..It doesn't shift hard at all(never has).

We've checked my tune multiple times and there is now TM left and the line pressures are all the way up for WOT shifts.

Anyone have any ideas??

Sounds like you might be having a band failure. How does your fluid look and have you had the pan down to check for debris in the pan? You could try to install a shift kit and also tighten up the band if all looks good inside the pan. Vince

No, I haven't dropped it lately.. Do the filters on the trucks need to be change when you flush them?

Adjusting the band and adding a shift kit can both be done w/the trans in the truck. Right??

How much are shift kits and who makes a good one?

I always recommend changing the filter when a service is done. Even when flushed. We sell a kit made by transgo. Here is a link for you. http://finishlinetrans.com/store/pro...products_id=86
