I put 1/2 can of SEA TUNE form Sea Foam into the transmisson. ran to town 15 miles away, let it sit over night, ran to town again in the am came home and drained trany. I did the Transmission FLUSH!! Wow Am I glad I did!! I really think it helped get the gunk out and since then no problems. we took the horse trailer w/ 2 horses and It ran Lots better. SO far so good. Also this am i put some sea foam into the gas tank & drove to work. no problems. :amen:
