I'd suggest maintaining use of the 50/50 blend of Redline MTL and MT90. Why? Because Nissan technical specs still call for a 75w85 lubricant for maximum performance in any climate. Keep documentation of your use of this synthetic combo, as this will maintain not only your tranny, but also your warranty!

When I filled up the tranny it didn't overfill like you stated. I was a bit concerned since I did spill some of it (1/8 of a quart) when I missed the fill hole. Also, when I jacked up the car it was from the passenger side alone. Should put another quart and fill till it flows over it or will it be fine?

It didn't overflow because you didn't have the car jacked up level. I wouldn't worry. Just fill it to factory levels and you should be alright!

Thanks Steve!

No problem!

When I changed my transmission fluid I only jacked the front of the car up, so I didn't get any overflow either. Just make sure you compensate for some of the fluid left over in the bottom of your bottles and any residual amounts left in your pump. I think the car takes ~3 quarts so I went ahead and opened 4 -- 3 full quarts and a little bit of the 4th.

Zeto · 02-07-2010, 11:32 PM

Yea, I mean the Z is running fine and the shifts are smooth but I'll go ahead and follow in your foot steps and get the 4th quart and use a 1/4 of it.

m4a1mustang · 02-07-2010, 11:34 PM

That should work out. I think between spillage and residual fluid I left behind around 1/4-1/6 quarts.

I'm amazed you guys can estimate how much is left in your pumps. The Autozone pump is an absolute POS and a complete mess. For next time, I think I'm going to get a Motive fluid transfer pump. Over the life of my car, it's worth the $60.

Just changed my transmission oil today. I used 2 blitz rhino ramps to lift up the front wheels then I used 2 jack stands to lift up the back wheels (4 point lift). I got underneath the Z very easily with that set up.

I also used measuring buckets to make sure I was putting in the right amount transmission oil (3 quarts).

Similar to these (can be found in paint section at home improvement stores, I got mine at LOWES for $2.50):

Shifting does feel smoother throughout however I can really feel the difference going into 1st and 2nd gear the most.

Thanks again Spearfish!

quick question: if I was running whatever stock oil was in the tranny before, should I flush it before using redline oil? Or it prob wont matter I am guessing? (I have a manual tranny btw)

Zeto · 08-31-2010, 02:54 PM

Theres no need to flush. Just drain all the fluid out, close up the drain plug and pour the new stuff in.

Chico370Z · 08-31-2010, 02:58 PM

ok, thanks! that's what I figured...I would prefer to not flush it imo

Someone pointed out earlier that they could not find the dipstick for the transmission fluid in the automatic. I'm having the same problem. Any help?

Thanks.

I think that it is a sealed tranny, you don't check it or add to it. It has to be flushed and filled, but I am not a positive. But I'm sure some one else must have done this already?
