Redline MT-90 in SR Tranny

[Carlwill]

I am wanting to swap out the crap that is my tranny and use some Redline MT-90 but I am not sure if it's a good idea to flush the transmission with something before I fill it with the Redline. Does anyone know if I should flush the tranny and what should be used before adding Redline?

Thanks for any info.

flush it out with 10w30 if you want. but i just swapped my old shit out with penzoil? syncromesh and it feels great. no more grinding or rough shifts.. just me .2c

no need to flush. just fill it up and roll

I highly recommend the redline, mt-90, or even something like redline 75-90. You really can't get anything too wrong weight wise unless you're using it for real specific applications. Just don't get heavy duty shock proof.
