What Transmission Fluid Do You Use?

[firefighterwhite89]

For years, I've always ran Castrol GTX 10w30. That's what the manual calls for. I can't believe i never discovered this synchromesh fluid until now. After reading on it, I'm thinking that's what i'm fixing to use from now on. Is that a good idea?
Seems like most everyone swears by it and claims it's better for our transmissions on older Hondas. Any truth to that? Anyone had any bad/good experiences with it?

The Honda MTF works just fine for me.

I've recently heard that this Honda MTF has synchromesh in it and lubricates everything much better than the stock Castrol GTX it calls for. Any truth to that? I'm trying to figure out if it is worth the price hike...

I can't say if it has syncromesh per se, but it definitely has some kind of special additive to smooth out shifts. Most everyone here swears by it. Definitely worth the money in my opinion.

Thank you for the input. Seems like nothing but excellent reviews

That is exactly what ive heard about both of them. they are on par with each other and have gotten rid of the 3gear grind from plenty of hondas. Id say go for it. Ill prob be running honda MTF soonish.

Not sure if synchrmesh is a trademark name or what, never heard of it otber than the word itself describes a style of trasmission where tge gears have sychronizers which are "sub-gears" teethed rings that are either side of gears that help smooth mainshaft enguagement with gears. Somebody correct me if thats not a good explaination.
Any friction modifier would do the same thing as your additive firefighter, examples would be the trusty ole GM limited slip additive pn#88900330 and additives that you add to standard gear oil in positraction differentials and that claim to smooth torque converter shudder in automatics.

Been running GM synchromesh with a lil bit of lucas oil stabilizer for more thickness and to 'cling' better on the 5th and reverse gear which ive heard are high up in our transmissions so they dont get as much lubrication. Never any probs here

I am running Honda MTF with I believe Molyslip addative... It helped a lot and shifts nice and smooth now.

I run honda mtf (no additives) in my 89 lxi coupe automatic. Works great...

I wound up getting Valvoline Synchromesh fluid in the Blue bottle for $7.99/quart. You guys are right. This stuff is magical somehow. Shifts like butter. That annoying third gear occasional grind is gone!

Castrol VMX80 in my B20A box with quaife LSD. No noises no crunches shifts like new and gets raped daily (Y)

I run the 1st gen honda mtf oil. You can ask for it at the parts counter

Honda MTF in the 89, had to flush it twice to get the power steering fluid out after the speed sensor rebuild.

I've been using Red Line MTL in all Honda's for many years. I don't think the 3g is picky as long as you keep it full to cover 5th gear!... Had a 1987 Civic wagon that went 380K+ miles and the transmission never had any issues, shifted smooth as new, never opened up. 2005 Civic was notchy going into second brand new. I gave it 5k miles to break in, no improvement. Switched to Red Line MTL and within a couple hundred miles was shifting smooth. What a relief! My 88 Accord shifts same as it did new, now at 164K miles. I change it at 30-40K miles.
