Great experience
Dealership gave me the wrong fluid twice and said they couldn't order the correct fluid so we just went aftermarket. Fluids came fast and in good condition. Car shifts much better now

Hard to find a decent fluid for nv4500 cheapest I’ve been able to find it.

Best price on this stuff after searching the internet
performed just as expected. If this is the fluid you need, Red Line is top notch and will not disappoint. This went into my 97 Jeep wranglers manual transmission, it helped smooth our the feeling of a sticky synchro, and provided less gear box noise. A++ to amazon for the great low pricing on this fluid

Used in my G35 manual transmission
I’ve changed it at least 3x in its lifetime with this same fluid. Works well when the temps drop below 30F
