Can you guys think of a reason that an external ph8a filter i attached in line with the tranny would cause the fluid to foam?? i'm not positve that that install caused it, becuase i changed a bunch of things at the same time. has anyone ever done this mod? too many variables for me to sort out. Thanks

The main thing to cause foaming is overfilling. Make sure it is hot and level when you check the level

 

well i got some info from a tranny shop today that said that the c4 is particularly sensitive to valve body leaks if it isn't bolted down exacly right. so maybe when i took it out last time, i bolted it unevenly. when it has leaks, they said it will foam. i will go into the tranny this week and re set it. i'll keep you posted on my results! thanks

well, i talked to an autoparts store and they pointed out that a ph8a is meant for a high pressure system, like 20 psi and above, but a tranny only puts out about 7psi. also, the b&m kit said that if i was getting foaming the cooler or cooler line was probalby clogged. I'm guessing that the oil filter was "clogging" it. i removed it but i still have foaming, even after re-checking the shift kit install. I'm gonna try bypassing the stock cooler with an aftermarket cooler, just in case the radiator one is clogged. i'll keep you updated.

The Magnefine trans and power steering filter is a great product and is made for that application.
