my 93 sc300 5spd has 170 000 and i thought it would help if i changed the tranny fluid, who else has done this, did you notice any signifacant improvements, also im not sure, but can you just drain all the fluid from the drain plug unlike a auto tranny? and one last thing, what would be the best tranny fluid and weight to use? thanks in advance

 

Manual trans fluid is almost like an engine oil change minus the filter. Drain and refill. There is a difference after the change= shift feel.

 

yea cause if i downshift i have to give it a lot of force to get it into first if im going like 10mph in second

 

Where would you refill this? Through the shifter?

 

there is a drain port and a fill port... drain it, put plug back in, fill til it pours back out the fill plug...

 

i wanted to this because i cant downshift into first unless im going 5mph or less, but no grinds, im thinking maybe a synchro wearing out? what would be the best mt fluid to put in, i hear a lot of people use redline 90wt, what do you guys suggest?
