How many quarts do I need to buy to replace the stock tranny fluid? Yes I know a stupid question for most but I thought I would ask.

+1

I was wondering the same thing!

The only stupid question is the question not asked.
 
Does it need a flush ? I would think not but I would prefer to be sure and I do not have my copy of the book yet.
 
dont flush your tranny. ever. its horrible for it. plus you have a brand new car. just empty the old fluid. and put your new s*** in. the mt-90 fluid rules.

16000+ how come ? and maybe I miss spoke Will the the new fluid have a bad reaction with oem fluid. I figured it would be fine. Tell me how is the pricing compared to amsoil and Purple? thanks.

MT90 is about $12 per qt. You can find it online for less, but with the shipping, it may not be worth it.

No issues with adding it without a flush. It is just like motor oil, it will mix just fine with whatever is leftover after the drain.
 
MT-90 is the best you can buy!!!!! No other tranny fluid will make it buttery smooth like Red Line...

Its worth every considering you won't have to replace it for another what 20K-35K (no sure, but a long time)...?

What other trans fluids have you tried. By the by. I will try a new lube but I lean towards the purple synchromesh. I will look deeper but mt is on the list. thanks
 
three when changed definitely. i filled mine until it ran out of the fill plug it ended up being something like 2.7. so when your on your third go nice and slow toawrds half way. and royal purple is ******* god! that s*** is awesome for sure but its like a few dollars more per quart or oil than sytec oil. not sure about the tranny fluid but im sure its no different. youll be thrilled with redline....i know i was and still am.
