The transmission has been working perfect for the last 25,000 miles!!!!!!

My 1999 Subaru Legacy Outback started to not go into drive or there was along delay. I heard that this is a problem that many people see with these older Subarus. So I decided to try your Transmission Fix along with changing the transmission fluid with Lucas Semi-Synthetic Transmission Fluid. Well right after the change in fluids the transmission worked better then before and went right into drive. It did however started to have a delay again after a few thousand miles so I did the same fluid change again and the transmission has been working perfect for the last 25,000 miles!!!!!! -John K.
