911 grinding 3rd to 4th - TriStateTuners.com :: Home of Tristate Auto Enthusiast

Our 911 Porsche still grinds a little going from 3rd to 4th. We did a trans flush and put in redline tranny fluid.

We are now considering additives. Any ideas? We were reading about "Syncroshift" and "Lucas". Which one or what else can anyone recommend?

I don't know the story behind this car, but I wanna say it's the synchro.

I know, and appreciate the input but that was not the question.

if there is a mechanical problem all the additives in the world won't make a difference.

Sounds like it could be a synchro... they love it when the oil is gooey and thick. Try putting heavier fluid in.

I heard some great things about Synchromesh

+1

Try the additives anyways. I don't think it will help but at this point it's not really going to hurt either.

btw nice RS3 in your avatar

OMGz Turbo · 04-21-2009, 01:00 PM

cszakolczai · 04-21-2009, 01:08 PM

Well I'm glad I read this thread, can someone say the best place where to pick up synchromesh? I am going to change my tranny fluid soon.

OMGz Turbo · 04-21-2009, 01:21 PM

pepboys lol

Tires2theSky · 04-21-2009, 01:36 PM

i have to agree all the additives in the world aren't gonna fix ur prob just hide it.......fork out the money and just fix the tranny before something else goes wrong and u lose the whole tranny

AutobahnRacer · 04-21-2009, 02:10 PM

tranny was already rebuilt not too long ago. Ill give synchromesh a try

alwaysinboost · 04-21-2009, 02:43 PM

snycromesh isn't magical or anything, I've used it before. If you're using the type of fluid that recommended for your trans and its still grinding you've likely got a mechanical issue. But hey, keep changing your fluid if it makes you feel better.

bl@ckvr4 · 04-21-2009, 02:48 PM

I run synchromesh in Getrag and I love it. But what I meant in my first post, is that if your synchro is defective, it won't matter what fluid you use, it'll still grind.
