Changing out manual transmission fluid on my Civic

[Grinche]

I have a 06 Civic SI with 20K in miles and I tend to drive it pretty hard. I was thinking about changing my transmission fluid over to synthetic...any down side or recommendation for doing this or not doing this.

Why do it your ask? Driving habits and just plain makes good sense for the life of the transmission it would seem. This car does have a third gear shift issue were it pops out of gear..it is not uncommon on this car becausce of the shift pattern..my neighbor has an Acura that does the same thing.

Any manul tranny fluid you folks would recommend?? Thanks all.

I use Redline MT90 GL-4 synthetic in my 2006 Corolla, changed factory fill at 4k miles. Chnages are very smooth, now have 10k miles and will change every 25k miles from now.

My 2006 Scion tC calls for any GL-4 75w-90 gear oil.
I went with Redline MT-90 synthetic, and I am very impressed.

Shifting-feel has improved, much easier to shift in cold temps.

Sure, I say go for it: Amsoil MTF

Probably should move this to the tranny forum.

I use Red Line MTL in my '03 civic and love it.

MT-90 is a large step-up in visc. I changed to Redline MTL in my 06 RSX at 7500 miles and liked it enough to do it again at 40k.

Grinch, I've got the same car and had the same issues. Went to AMSOIL MTF and all problems are gone. You're gonna like it a lot!

If Specialty Formulations is up and running again, I'd sure check out their offerings.

How do I find out how much fluid my tranny holds??

 

[unDummy]

Read the owners manual or factory service manual.

A lot of the oil companies know this too, if you can't find a service manual. I know that the guys at Redline know, anyways. Once I emailed in to confirm a driveline application and they also responded with the capacity.

Redline MT90 GL-4 synthetic in my Toyota.

Awsome fluid that is miles ahead of the OEM fill. I changed mine out @ 10K miles and the shifting is now like butter!
