I have a m6 and the shifting is kind of difficult until the car is warmed up. Do I need to let the car warm-up so the hydraulic fluid becomes more flowing?

 

Well if shifting is difficult until it's warmed up...I would let it warm up...

 

I can shift, it is just not as free flowing. I ask about warming up the car because I have read on this forum that warming up the car can be harmful, is it?

 

warming up a car is exactly what you WANT to do, let things come closer to operating temp and get those lubricants flowing before you add a heavy load to a cold car

you dont need to let it run forever, but if the weather is freezing, atleast give it a minute or 2 to get going

 

No way warming up a car in cold weather is bad for it. flip on the defrosters and let it warm up man.

 

No.

 

I have no problem letting my car warm up for 10 minutes if that's what it takes to get some heat out of the vents! Seriously, my dad is a mechanic and actually recommended me letting my car warm up for a few minutes until the sound of piston slap goes away. I know that not all cars suffer it as bad, but mine has been pretty noisy since day one, so I let it warm up for a few minutes each morning (especially now in the cold CANADIAN winter!!).

However, I don't think your M6 will warm up on its own with the engine running...................nothing is turning inside it 'til you get moving, so that will just take getting used to the sticky cold shifting.

 

Ahhh, YEAH!!!!!! When it gets really cold your oil is like molasses. By putting a lot of load on the engine before the oil is warm increases wear on all moving parts.

 

It's a classic argument that never goes anywhere. The other theory is that by cranking and going, you fluids heat up faster thus causing less wear on the motor. Personally i like a little heat, so mine warms up a bit before I leave. The other guy was right though. The tranny fluid dosent move till you do, so your stuck with that one. Nice car SS1LE02, I guess I'm partial.

 

Actually the input shaft is moving inside the trans when the clutch is released.
Although it would take forever for this alone to warm up the trans.

Also the heat from the engine finds it way into the trans but that will take a while as well.

Bottom Line:
The only way you're going to warm up your transmission is by driving the car

 

Oh yeah, you're right! I somehow didn't think about that in my last post. It's really no different than an automatic, which will be turning the input shaft while idling in Park.

 

which you pop into nuetral to warm up

 

My car has been outside running for 10 min......its 45 deg outside........I slid under the car and put my hand on the trans.........its kinda warm....not as hot as the damn oil pan...haha

 

Yea the M6 tranny will only warm up by driving it. You could let it idle all day and it won't do squat. Up here when its -30 (like right now) the T56 never warms up. One night I drove the Z around for like 3 hours in stop n go traffic, then when I went to race someone on the highway you could tell that the tranny was still cold they way it sounded & vibrated

 

I drive my car year 'round and have never let it warm up for more than a few minutes. I usually don't even let it go that long. I;ve never had a problem with it. Well, rear end noise but that happens all the time. Anyway. On Monday it was -2 on my drive to work. I had let the car warm up for about 3 minutes. The stick seemed to move a little slower than usual, but just for a few minutes. Excessive (>5 minutes) warmup is not required. Just don't beat on it right away.
