I have a 97 pickup with a 5.9, auto that is starting to slip, it was a rebuilt around 2009. I was wondering if there was and tranny additive that I can put in for a quick fix, till I can get it in for a rebuild.
Thank Ya Guys.

 

Mmmm using an additive could end up making the rebuild cost more and it might make you need to rebuild it much sooner.

I don't know what to suggest to you for an additive. Check the bands and a fluid change.

 

I know I'm outnumbered by a lot here, but I've had my tranny power flushed twice in the 64,000 miles I've owned it (now has 147,000), not a single problem knock on wood. Yes twice is a bit over kill in 64,000 but hey I'm still on my original tranny and its holding strong...

 

I to am on my original tranny, 187,xxx and not one noticeable problem; the guy I bought my truck from at 75,000 10yrs ago did a tranny service at 40,000, and that's all.
