Since it has been getting colder outside my car is becoming a problem. I have to warm it up for around 15 min. for the car to even go into gear. Not unitl the car is at a constant temperature will it allow me to shift into gear without trouble. I have also noticed that the the transmission is grinding more frequently when I try and put it in gear, mostly first. What do you think the problem is?

 

when was the fluid changed last?

or the clutch?

could be bad syncros.

 

that's happening to me too..bad Grinding. I changing out the fluids today..and might buy a new clutch/flywheel combo soon.

Damn you weak SR trannies..anyone get that z32 swap mastered yet?

 

Old car with cold weather=poor performance. You might try changing out the fluid and adding a quality tranny fluid, not just 80-90 gear oil. I live here in Ohio and it's been 10 degrees lately and some other people I talk with on another site have had similar problems. I can't remember the name but I'm sure someone on here can help me. It's not cheap, either, but it works. If that doesn't work make clutch/clutch adjustment or just worn out tranny.

 

So what you guys are saying is that the fix might be as simple as changing my transmission oil? I haven't changed the oil since I purchased the car about 1200 miles ago so I guess I'll put in some synthetic. Any one have any suggestions for good synthetic transmission oil?

 

ya dont use it unless its red line

i use valvoline 80w90 organic

 

Automatic transmission solve this problem by using the engine to warm up the transmission. The oil line from the transmission passes by the radiator core, thus when the radiator water warms up, so does the trans. If your car has a Manual, and SOMEHOW you find a oil line, you can get a radiator from an auto and hook it up. But I've never heard of something like this beign done, so it would be a first.

 

^ no its to cool the trans down.

not heat it up.

 

while were on the subject, im changing my clutch soon and its time for new tranny oil...and suggestions on good tranny oil? Ive heard redline and royal purple are both good, also what viscosity and amount is needed (sr20 of course). ps sorry for kinda jackin ur thread

 

That's cool, no need to make two threads on similar subjects. I my question is the same just for the maunal trans behind a sohc ka.

 

This is the oil i use in my SR and my KA
