The Most Common Cause of Transmission Shifting Problems

If your vehicle’s automatic transmission isn’t shifting like it used to, you might be wondering if a large repair bill is in your future. Transmissions are complex and repairs can be costly, but many common problems, such as delayed or hard shifts and slipping, can be prevented or fixed without a trip to the shop. 

Most automatic transmission problems, especially in high mileage vehicles, are caused by sticky varnish residues that form in transmission fluid over time. Changing your fluid at manufacturer-prescribed intervals is important, but even that might not eliminate the buildup of deposits that can diminish performance. 

The Sea Foam Solution

Sea Foam TRANS TUNE is a safe, simple solution to common transmission problems. It works fast to reliquify varnish deposits from valve bodies, solenoids and shift actuators, restoring the performance of your transmission. It’s compatible with all conventional and synthetic petroleum and mineral-based automatic transmission fluids. 

How to Use It

Start your vehicle and let it run until your transmission is at operating temperature. Then check the fluid level to make sure the volume does not exceed the manufacturer’s recommendation. In most cases, you should not have to drain any fluid to use TRANS TUNE properly. 

Add one pint (16 oz.) of TRANS TUNE to the transmission filler. When adding before a fluid change, drive at least 30 miles to circulate and clean before replacing fluid. When used as a cleaner or conditioner, add TRANS TUNE for the life of the fluid interval, again making sure the volume does not exceed manufacturer specs.
