Transmission fluid

[mot250]

A Royal Purple rep told me to use their Syncromax for the 2005 and up manual 5 Spd.

AWSOME! Thanks will be heading for Autozone on the way home!

Whats the usual change interval on manual transmission fluid?

Wow this RP is expensive! 20.00 a quart!

Amsoil Synthetic ATF (the recommended AMSOIL product for the 5spd manual) $11.50 per QT.

Just looked through my 2006 Owner's Manual and Maintenance schedule...nothing references the change interval for the fluid in the manual transmission. The Maintenance Schedule stops at 150,000 miles. But somewhere I remember reading/hearing 100,000 miles for normal duty on the manual trans fluid before a change is recommended.

However, based on how mine looked when I drained it at 9,000 (lots of break in wear particles, heavy metalic shimmer to the fluid I drained out), changing it before 100,000 would never be a bad thing. After that inital change, then you can probably safely go at least another 50,000 to 100,000 easy before another swap if you fit in the "normal Duty" category.

Proab will change mine every other oil change on the FR and once a year on the street 05.

I'm going to change mine more as an upgrade rather than a maintenance thing. I'll worry about it again if and when the transmission ever needs to come out of the car.

About how many miles would that be between changes?

Regardless, that sounds a bit excessive. If you are going to do it that often, I'd suggest you get the first few fluid drainings analyzed for the amount of wear particals then adjust the drain interval based on those findings.

That was my initial reason. Then, after seeing the condition of the factory fill at 9000, I wanted to see how the RP looked after about the same amount of time. Later, I just wanted to upgrade to the AMSOIL.

I kept samples of each draining if I ever feel inclined to get them analized.

So I seriously doubt it would help at this point for me, but if I changed my fluid would it help with very worn synchros? My second gear synchro is all but worthless, I've stopped using the gear to try to keep the tranny alive a bit longer.

Scratch that. Synchromesh did nothing for me. Shifts on 3-4 don't feel any better either.

Well like I have said before the FR is my first car build I have always raced bikes so I am using what I know from that and trying to put it over to the car. After every race day we drain and flush the fuel system, new brakes, oil, filter, tires, plugs, new clutch, sync the carbs/throttle bodies etc. After every weekend we do the same thing but also check/adj valves, check compression, change fork oil etc. If we have a month between races we freshen up the engine, rings, head gasket, bearings etc. I just figured with racing the car it would be a safe and good preventive maintenance.

My ford dealers said the mercon V never needs to be replaced. hmm.

The same dealer who might want to sell you a new car?

For an all out competition car, maybe the more frequent trans drains/refills may be justified if that's what your doing. Sorry if I did not get that from your other posts.

But for a DD or part time use driver/fun car, I still think yearly manual trans fluid changes are not necessary. Maybe if your getting 50,000-100,000 mi a year, maybe.

It is great to get the factory fill out as it has all kind of break-in particles in it. Or if the trans has other problems or has been driven with a lot of missed shifts an grinding. Otherwise, it should not need to be changed out all too often.

That's just my 2C. That's coming from a guy who's changed his out 3 times in 50,000 miles. Just based on the visible condition of the last two of those I'd say two more times than were necessary.

But to each his own.

Your probably right. I'm not going to be racing a series with this FR it's going to be a track day car and just to drive to car shows. I proab don't need to go overboard on this. I will put this stuff in and then at the next oil change drain it and check it and if everything ok proab not change it but once a year. Now I just need to pick a clutch n flywheel so I can put it in!

 

[skwerl]

If you need to change the transmission fluid once a year then you need to replace your transmission because it's broken. Once every five years maybe.

I use Royal Purple.

+1 Royal Purple Synchromax transmission fluid. We use it in our Corvettes too - better than the GM Syncromesh fluid. Worth every cent!
