anybody changed out to synthetic oil in their Type R tranny? If so, what are you running (brand, grade etc.) thanks

 

I've had good luck w/ BG Syncroshift II, but now I've gone back to Honda MTL, just because it's more readily available, and Mike K @ Naples Acura gives a good discount on it.

I've been curious of the Synchroshift, however have been hesitant to use anything but Honda MTL. I figure, it's easy enough to change, and you can't go wrong with what the factory uses. Of course with engine oil, I'm a big fan of synthetics. I hear the B18C5s like to burn Mobil 1, but to my B16, it's liquid gold. (I haven't burned an ounce of the stuff after 76k.)

 

In the Civic, I use Redline MTL. Try it. You will like it.

 

Most ITR owners have complained about Redline MTL in their gearboxes and put Honda MTL back in. I have BG Synchroshift in my ITR and it works great when the car and/or weather is warm, but the gearbox is a little notchy when cold and I have to wait to grab second on those chilly morning shifts until I get some heat into the car or I'll grind the shift.

I think I'll swap back to Honda MTL when I do my next tranny fluid change. The BG is good stuff, but for people who live and drive in colder climates, I'd stay with the OEM Honda fluid. Just my $.02

 

Redline MTL. I searched this about 2 months ago and the concensus was that if I put redline MTL in my transmission, it would blow up. (not literaly) SO of course I went ahead and put it in anyway, and I'm relatively happy. Smooth shifts, quiet operation and the annoying refusal to go into reverse and 1st gear is less severe.

 

I use Redline and I have no complaints. Be honest, I wouldn't use anything but. be careful what you use in the summer on a hot, sunny day. Your trans temp will get pretty high with the temp of the track, engine heat, trans heat build up, etc.....

 

What did the ITR guys not like about the Redline? Two teams I have crewed for used it in their (ITR) cars. Just wondering. Thanks.

 

I tried the Redline MTL in my '97 R about two years ago for Solo 1 events and was very disappointed with the results. I experienced difficulty downshifting, especially from 3 to 2. Went back to Honda MTF and eveything was good again. I don't know how much truth lies in this but I've heard that the Redline fluid actually may be too slippery (??).

 

From what I have read, many of the synth gear oils act funny in the cold. The common complaint with the Redline is notchy shifts in cold weather.

I use Mobil1 in my RX-7s tranny with no prob so far. And use Redline in the diff.

 

"but I've heard that the Redline fluid actually may be too slippery (??)."

Transmission oil can, in fact, be too slippery.

Synchronizers are essentially friction clutches. They use friction to accelerate the inputshaft/disc up/down to mainshaft speed in the gear selected. So, if you lubricate them with something too slick, or something that is incompatible with the synchro surface, it will not accelerate the shaft and thus will not go into gear.

 

Nice...

i am running valvoline gl-5 synthetic lsd oil.

 

what weight is the Valvoline lsd synthetic you are running?

 

redline MTL. no complaints. shifts smooths and no grinding.

 

even though i don't have an R, i do use Redline Syn, and i'm going to be switching back to Honda MTL or trying BG Synchroshift... with Redline, 5th gear grinds about 70% of the time, and 1st can be real fussy... however, i'm not sure if it's the Redline or a stubborn throwout bearing...

now, my question for you all is how are LSD tranny oils any different? are these designed for certain types of LSDs?

 

75/90 weight

 

stock is the best

 

i agree BUT, i have a clutch type lsd, so stock doesn't work for me.
