Yep, had one of my techs do my Jeep today and added some conditioner.

 

Valvoline is the way to go. Your shifts will be so much smoother

 

Has anyone used Castrol ATF +4 ? Any opinions ?

 

OK,, with all thats been said,,, syn fluid is REQUIRED ,, so its not likely that p-owner mixed fluids. BUT if I do a tranny fluid change (atf4+) &filter myself, theres ALWAYS that gamble .
Last question,,, is there a drain plug on torque convertor.
To eleminate the gamble have it power flushed, right!!!!!

 

It's not a 'power' flush. The fluid is pushed out and pulled in by the trannys pump. A cleaner is added to help break up dirt in the filter and throughout. This flush is really a complete drain and fill.
The common misconception is "this power flush will cause stress on my tranny internals then cause problems."
The truth is, some tranny problems are hidden by dirt and build up and after a flush is done and all the dirt is gone, these problems start to show. If you have had no tranny problems and been having it serviced regularly, there will not be any problems with flushing, every 30k or 5 years.
