Castrol TRANSMAX Trans Fluid

My Brother in Law said he was going to put the Castrol Transmax DEX/MERC in his 92 E4OD trans this weekend. I don't recall if it is recommended. Pls advise before he adds it.

Recommended? No clue. I *generally* don't like multispec ATF. But I'm sure Mark will chime in with actual information before long.

Thanks. Recommended or safe to use. Or what should he use.

To the best of my knowledge, Ford is recommending Mercon V for the E4OD.

Thanks again. That's what I thought but the FLAPS guy told him it was OK. I'll tell him to use Mercon V.

He gave me the phone number on the jug for Castrol. You are correct the IMPORT Transmax is what they told me is recommended. Thanks for your time.

This sort of thing is *exactly* why i don't ever trust multi-spec ATF. Is it gonna work? Probably. Is it going to shorten the life of the transmission? Maybe? I just don't know.

He is exchanging it tomorrow (weather permitting) I am leaning to what yall are saying. He just needs to go with MerconV and be done with it. I wouldn't put that import stuff in my E4OD.
Thanks guys I appreciate your time to help,.

Frozen north of you in DFW...Mercon V replaced Mercon. I put cheapo stuff in my 4R100 over the summer, has not died and shifts fine. It was some basic Wallmart stuff called 'Universal ATF'.

I have used a lot of Mercon five past few years and hasn’t done me wrong yet.

Sure there’s only a handful places that actually make the stuff but why not spend a little extra for motorcraft’s QC because after all transmissions are an expensive pain in the butt to replace.
