I'm going to be installing my transgo shift kit and wanted to get some feedback on the type of fluid I should go with. My specs say to use Mercon V. What about synthetic? Any comments guys?

Thanks in advance!!!

I can tell you I used synthetic in my Mustangs AOD, I could only find Castrol at the time, after a while, I thought the tranny was hurt, and just for a shot in the dark, I desided to try changing the fluid.
I drained the converter and all, and replaced it with Mobil One, night and day difference, get Mobil one if you go syntheic.

 

When I did my Transgo kit a few weeks ago, I drained the torque convertor and filled everything back up with Amsoil synthetic. It's a bit expensive at $8.00/qt for 14 quarts, but I think it's well worth it.

Thanks for the info guys.

Thanks Ruger!
At this point I'm going to go with the Mercon that Ford recommends and see what happens with the transgo install (goes in this sunday ). More than likely I'll start converting the engine oil and tranny fluid over to synthetic. When I do, I'll look you up again for some questions.
