Not knowing when last my 98 had an AT service, and I was at around 115K miles, I decided to drain and refill... changing out the filter as well. My research revealed very specific instructions incluidng car level... laser thermometer... everything down to a T.

I purchased the OEM filter and most specifically... The Pentosin 1. I did copious research on alternative, and less costly, fluid... but was reminded and encouraged to go Pentosin.

The car had NOT been acting up... but I wanted a benchmark moving forward.

Before embarking on the task I was 'warned' that shortly thereafter the transmision could fail.










Shortly thereafter... within a couple tousand miles... the transmission main seal failed.

$4,300.

OP... be certain to keep us posted, and don't go ghosting us when you hit the side of the road.

Me, based upon the comments you've inspired, would be taking the car to a shop and having the transmission properly serviced. Good luck.
