have an 1998 W/ 131,000 miles going to change the torque convert

er fluid as well, can I use seafoam cleaner to help wash out deposit's built up. There's not been a flush done yet. the motor is a 4.6 have read post's about pulling the line off the tans cover and purge it that way. I already replaced the filter and added 4 new quart's, sound's backward's I know, but if I new then what I know now I would have flushed from the beginning. thx

 

You can use Seafoam Trans Tune. I've read good things about Seafoam in the gas and PCV line, but haven't heard much about their Trans Tune. I doubt it'd kill your tranny.
