M/T CCOLD!

[FReddy]

Transmission is TIGHT in cold weather. Thinking about a lighter weight gear oil. First and second is hard to engage in cold weather.
Any suggestions?

shift over 3500rpm in very cold weather and it goes a lot smoother. also running MT-90 from redline.

PLEASE do not rev your engine to 3.5k before you shift when your engine is cold. Once it passes that first bar on the temp gauge do as you please, but your trans will likely be somewhat better by that point anyway.

I agree shifting above 3000rpm with a cold engine isn't a terribly good idea. I'm using MT90 and cold shifting is a little stiff but it goes away quickly. By the time the needle is above the low mark the transmission feels much better.

The factory fill doesn't like to cooperate when it's cold, different fluid will definitely help but I'm a little wary of the thin fluids at the edge of spec or thinner.

You know that bringing the car up to 3500 rpm won't really make any change....

It is better to keep a light throttle all the way up to 3500rpm, then shift, then put even greater load on the engine and shifting it at 1500 rpm..

Do not do as you please, just because you water temp is up to operating temps does not mean you oil temp is.

Your water temp can be 120 and the oil in the engine at 60-90 takes quite a bit for the oil to warm up.. I recommend a scangauge really helps see your warm up times and how hot the car runs under loads!

Wrong. When the engine is cold the effects of RPM are far more detrimental than when the engine is warmed up. Cold oil on a wrist pin is a fine example. The "twist" exerted on the piston from rotational forces of the rod are not exactly good for the engine when the pistons have not fully warmed up and developed proper piston/bore clearance.

Of course throttle should be kept to a minimum as well, but that is beside the point. In my original post I should have been more clear. When the engine is warmed to the normal range you can certainly rev it to 3.5k before shifting (everything has obtained sufficient heat for that). Do not go balls out until your oil temp is up though.

just drive the car for 5-7 minutes and its fine. its normal and there is nothing you can do about it. Coming from someone that has a 500 gram knob, aftermarket shifter, amsoil fluid, positive shift kit and the rear stay bushing.
