    Well, I would try that first before I jumped to any conclusions.

    I will be changing the fluid and filter soon then, until then the truck just sits [​IMG]

    I've actually got 152,00o on mine. And it has just now started hinting of problems.

    try this, after you have been driving a while and have your truck good and warmed up. check your fluid and smell it, if it smells burnt and is a very dark or blood color then you have an internal problem in your trans. changing fluid will help but sooner or later it needs to be replaced. good luck

    I put a quart of B&M trick shift fluid in my 700r4 when I change the fluid. It makes it shift smoother and quicker. On a 700r4 you should change the fluid once a year. they dont like dirty burnt fluid. it should always be nice and pink if not change it soon

    How many miles has it been since you serviced the tranny? Reason I ask, is if it's way over due the deturgent in the new oil will eat up your soft parts in there. On a tranny that hasn't been serviced in a long time it's better just to keep the old fluid in there and just start saving for a rebuild. It's happened to me twice where I'll buy a truck and do all the service that it needs just so I know when it was done and then about a month or two later, it's getting the tranny rebuilt.
    If it's been serviced like it's supposed to, then change the tranny fluid, put an additive in there that will make it a little slicker, and see how it goes.
    But if the fluid in there is brown and discolored, you might be on your way to tranny failure. The slick additive will help it to go longer.

    Imagine a cowgirl twirling a rope.
