CRX Si Transmission Concern

[bonespec]

I don't intend to completely hijack, but I also have a CRX. I can't remember 100%, but I believe the previous owner told me that Kaaz. He used (and gave me some extra) MTL, which I did a fluid change with earlier this year. It sounds like my next change will be to something different. What brand of stuff do you advise bonespec? It looks like Pennzoil for fluid, but it looks like a bunch of different manufacturers have posi additive. Thanks!

Pennzoil Synchromesh and Trans-X posi trac additive has served many well, 1.7-2 bottles of Pennzoil and 1/3 tube of the posi additive. Autozone stocks them side by side.

Just chiming in to say take bonespecs advice. I installed the 4.7FD early last year in my ITA CRX along with a refresh (3 new synchros and new shift forks). I tried the Amsoil Synchromesh, the one that says it works for Honda boxes on the label, and I got a crunch in 3rd. Same with Redline. Too slippery for the syncho.

Picked up the Pennzoil synchromesh and I've done 17 races on it now with lots of abuse and not a single crunch. I don't have a plate diff so I do not use additives.

Sean, whose 4.7 FD was in the tranny?

Please don't say ATS.

Seems last years problem was more than you thought.

I will see what I can find on the 4.7FD. Previous owner may have left me the receipts from the install though I am not sure if he put it in or not. I know he added the differential.
