The best Gear oil for your civic wagon rt4wd

in Engine & Drivetrain
i used to have a smooth shifting gear ripping rt4wd tranny but this summer i smacked it into the edge of a pothole causing me to have to replace the tranny , i found a used tranny installed it but have had problems shifting into second gear i get a gnarly grind unless i baby it .
long story short i been researching and researching and came to the conclusion
GM friction modifier or penzoil with friction modifier is the best according to online resources , also have heard many pros and cons about redline MTL and redline shock proof , So... since i can only use one i went with the Redline lightwieght shockproof.
after i purchased this i researched more and found a lot of negative feed back about the resulting damages to the ttranny causing it to make the synchros break down .
hoping thats not the case . here i go im gunna post some feed back after i run it today. any feedback from fellower hcwers?

    If your grinding 2nd than I would think it was the synchros. Go to Honda and buy their MT Fluid. Cost a little extra but well worth it. IMO

    thats what i had put in the tranny when i first replaced it thats why i was lookin for feedback on other ones i shoulda said that lol

    - upon first impression this stuff works i took it for a spin and drove calmly for about a mile and then i started ripping on thru the gears its a little slow but its definitely not grinding any more
    redline lightwieght shock proof gear oil has my vouch!

    What did you do with the old tranny? Wanna sell it?

    I might have to try that stuff in mine. My 3rd gear when down shifting likes to try and make noise. The rest seem fine. I might get some once I fix the small leak in my tranny.

    Redline MTL. My rt4 trans has close to 400k on it and it shifts perfect. I have been running redline mtl since 265k with no issues.

    Awesome news. How much is that stuff a quart?
  • phatrick2332phatrick2332 Band Wagon
    Anywhere from 10-13 a quart retail.

    I don't know if you were aware of this, but unless your car is at a complete stop reverse will nearly always grind. There are no synchros on reverse. The car (and the shafts inside the transmission) will need to be completely stopped for there to be no chance of grinding going into reverse. So come to a total stop woth the clutch pushed in, wait a second or so, and then select reverse. Otherwise, you are trying to mesh gears that are moving, and which have no synchros to help with that meshing.

    also always stop shift into second and then put into reverse had like 65 hondas and that seems to do the trick ' never get grinds

    If its grinding, and the clutch/ shift linkage are proper, than its syncros/ syncro sleeves. best way to fix this is not by masking the sound with thick oil. its by replacing the tranny with a proper one, or having yours rebuilt. always use honda MTF. theres a reason why honda makes it...

    Sorry to bring up this old thread. I've searched and can't find the oil capacity for the RT tranny.. I
  • FakeJDMEF8FakeJDMEF8 Senior Wagonist
    I believe it's 2.3 liters. Do you own a manual? It's in there - along with the Haynes. I'll clarify later today if I'm incorrect. Either way, get 3 and you'll have extra. Just fill until it starts leaking out a Lil.

    two things i have found thats helps with this.. first, from complete stop i put shifter almost in 5th gear (not completely), just as it starts to enter 5th stop!... then back into reverse. that has stopped the grinding for me... every time... i assume it does same thing as putting into 2nd (stops gears from turning) and i am only running house brand full synthetic 10w40 in trans.

    if that don't work, turn the radio up very loud... problem solved.
