Can I add Trans Tune to clean the tranny before changing the fluid? [SOLVED]
1 Answers
I have a 2007 Yukon SLE 5.3 with 185,000 miles. Transmission fluid has never been changed. I don’t have any shifting issues but I want to change the fluid. Can I add the Sea Foam Trans Tune treatment to clean out the tranny before I change the fluid? Will this damage the shifting?

Hey Miguel – yes, you can definitely add Trans Tune to the fluid before you change it. That will do a great job cleaning up any residues. Once you add Trans Tune, you’ll want to drive at least 30 miles before changing the fluid to give it a chance to circulate and clean.
Trans Tune is made with 100% safe petroleum cleaning ingredients and won’t harm your transmission or shifting.
