Hey, you guys have any specificbrand of ATF 4 that you use, or does it not really matter? Oh and, better to use Conventional or Synthetic?

 

your choice. ATF+4 is ATF+4

 

Most if not all is at least a GroupIII synthetic. Specs are very tight and not much different. Only way around that is if you goto a product such as Amsoil or redline where they do not adhere strictly to the standards and feel free to build what they feel is best.

Like Pennzoil then buy the yellow bottle. Like Mopar then get it. Buy the cheap stuff, all is well.

 

Last time I did a transmission flush I used the Valvoline ATF+4...no complaints from me.
