Hey, but at the end of the day, I'm just asking what fluid I should use in my next change. I used Castrol Domestic Multi-Vehicle last time around. I just want to make sure what I put in this time is agreeable. I do plan to drain both pan and TC, but still don't want to be mixing "baking soda and vinegar".

This is how you do it, this is the fluid you use...
It's easy to find and not ridiculously expensive...

[QUOTE=Mark Kovalsky;11581729]NEVER use MERCON V in a 5R110 transmission. It will kill all seven solenoids, and you don't want to know what it cost to replace all of them.
ok..clear as mud now! What goes into the 5r then?

Mercon SP has always been the trans fluid to use in the 5R.

Thanks! That's exactly what I was planning to use when I get my truck back from the shop. It currently has Amsoil ATF and I'm hoping that didn't contribute to the failure I had - only been in there about 25k miles.

I've talked to several master mechanics that really like for people to use Amsoil in everything. They won't sell it, they just like people to use it. It's paid for several kid's college educations.
