Best Transmission Additive
I just changed my fluid yesterday and want to change it again (since theres still old fluid in the torque converter). Search but with no posts, what in your opinion/experience is the best additive to add to a 700r4 tranny with ~150,000 miles?

Yes, and nothing will do the same thing as any additive you put in, but costs less.

The number one way to make your trans live longer is to make it run cooler. Trans coolers FTW!

external cooler.
basically a mini rad for your tranny that mounts infront of the radiator. You just strap it on, hook up the lines in series with the cooler in the rad (helps to get tranny up to temp faster and keep more constant temps) and your good to go.

Just about anything will work. The B&M coolers are good, probably the only good product B&M sells.

Lucas is a good product if your trans. is on its way out or has pressure problems, it seems to keep it going longer. If you don't have either of those problems, I'd say don't add anything else.
