SeaFoam TT16 Trans Tune 16Oz

After installing in my Transmission I didn't see any difference. BUT I don't know what is going on on inside my transmission so I will take the experts word for it is working.

DOES THIS STUFF REMOVE GUM AND VARNISH, IT SURE DOES, BUT YOU MAY NEED TO CHANGE THE FLUID AND FILTER. My truck is 24 years old and has 165,000 miles on it. It has the 4R100 transmission. Recently the torque converter went. So I had it replaced along with a complete ATF fluid filter change. Soon after I was still experiencing poor shifting, so I used the Seafoam. While it improved the shifting it created another problem. It was hard to put in reverse, stalled in reverse or hesitated backing up. Research told me this could be inadequate fluid flow, either from fluid lines and/or coolers , or dirty filter. I did a coolers flush using an air compressor and a product called Kooler Klean. My truck has two coolers, the one that goes through the radiator and another auxiliary cooler so I separated the lines and hoses and cleaned them separately. That helped a lot, but I was still experiencing a problem. Finally I decided to change the fluid and filter again. This was less than seven hundred miles after the new fluid and filter. After draining and dropping the pan , in the bottom of the pan was a thick goo about a half inch thick and it looked as if the filter was slimed up too inside the pickup. This stuff is said to dissolve and liquefy harmful gum and varnish. YES, it sure does, enough to restrict flow through the filter. In the end a complete fluid(16 qts) and filter change straighten everything out. I only wish I had used it prior to the torque converter and fluid change. I could have saved a $150. Will I buy it again, YES. But I will only use it prior to changing the fluid, putting it in about 200/300 miles before doing the change.

My transmission was making a strange sound when shifting from first to second and it no longer makes any noise when shifting. Highly recommend it.

Made the pump squeal. I am putting a new pump on tomorrow.
