while taking off from a stop i shift into 2nd, and sometimes i hear a rough grinding noise. this only happens when i shift into 2nd gear, and only when i shift around 5000 rpm+...and i know for a fact im pushing the clutch all the way down. what could be the cause of this?

umm, id try changing the trans fluid first..probably know already but use Honda MT Fluid. i had the same issue only with 3rd gear over the winter and i changed the fluid to Honda MT and it shifted smoother than when i got the car. so give that a shot and go from there

Think back to the last time you changed your transmission fluid... ....and I bet you can't remember, or maybe you've NEVER changed it, right?

Don't worry, most people with manual transmissions think that they can go to like 90,000 miles without changing their fluid, which is why they have grinds when they shift.

You should be draining and filling your fluid every 20,000 miles, and 15,000 if you race a lot. I suggest draining the old fluid and putting in Hondas new ADVANCED Manual Transmission Fluid. It has a bright green label and a white cap. Only 6 bucks a quart, and refer to your owners manual to see how many quarts you'll need.

Changing your tranny fluid is SOOOPER easy to do yourself, BTW. I think there's a DIY thread around here somewhere if you search. Good luck!

Probot

yea there is somewhere..i actually looked it up a couple days ago...you can just unbolt and pop out the speed sensor on the trans and fill there..just check to see how much it takes.

change the tranny first and if it still grinds after new fluid changed.then the tranny is grinding.are u running a d series tranny? if yes.it is cheap to get a good used one.

GM syncromesh works also that is a little more expensive?

Probot

there was a thread a couple weeks ago about what fluid to use and it said nothing but bad about GM Syncromesh.....i would just stick to the Honda MT Fluid

meangreenEG

the last time i changed transmission fluid was a couple 100 miles ago.... i guess it doesnt hurt to refill it again

Uh oh. Try the ADVANCED formula of Honda's MTF; it is Honda's answer to the GM Synchromesh Friction Modified, which really helps with grinds. It has a bright green label with a white cap.

My tranny used to be notchy, and now it shifts so damn smooth. Give it some time to work in, but if that doesn't take car of it, it sounds like you have some bad synchros. This means either a future tranny rebuild, or it's almost time to swap in a new tranny.

Probot

if it comes to rebuilding the trans or swapping...just swap, it will end up cost about the same or less depending on your mechanic and

and less downtime...rebuilding the trans takes longer

I agree.

Dont use the GM junk! Hondas new MT fluid is great and I love it! I have heard nothing but great things about it!

meangreenEG

thanks for the quick replies guys.

i will flush my tranny fluid out and refill. the grinding happens very occasionally but it wouldnt hurt to change it.

meangreenEG

and also, i dont know much about tranmissions, but would it be possible to swap in a b-series transmission into a d-series engine? i know that h2b works, is there such a thing as d2b?

you should also check all your mounts, my brothers car was doing the same thing and I figure it out his mount was broken and it was moving his engine and the car couldn't go into 2 gear at high rpm GOOD LUCK

Probot

no you cant use a b series trans on the d series...gotta stick to the d...and lets say worse case scenario you have to get a new trans..try to locate the trans off of the D16Y8 (2000 EX trans)...its the best trans for a d series, steel shift forks. and they are cheap as hell too 200 - 300 bucks tops

o ok...

is it possible to flush the transmission fluid as well as drain and refill, or would i have to take it to AAMCO or something?

Probot

if you are confident enough to do it just look up a do it yourself (DIY) or a how-to here on Honda-Tech and jack your car up and give it a shot or have a friend who CAN do it, do it...if not, just bring it somewhere. definitely wont hurt to bring it somewhere and if you can, ask to watch so you can learn how.

This stuff is ****.......It actually hurts a good transmission.

It made my tranny with les than 50k miles on it grind in 3rd and 4th....Switched back to honda AMTF and BAM...no more grinds and it feels 100% better.

Honda knows their own trannys best.

Bearings are probably going, soon it should start popping out of gear on its own, and then followed by no engagement at all. Save the gear and the synchros, all you will do is eat the synchro spring alive by trying to force it in gear, you will also wreck the slider and the gear engagement dogs maybe even overheat the hub.

Thicker oil is stupid, this only hides the fact that your tranny is going to ****, and in the long run, will only cause more damage that ISN'T audible.

Bearings aren't that expensive, and it's all that a honda transmission should need, provided you don't drive it like a jackass.

yep, why they require 10w30 SF/SG motor oil.

Anyone care to explain why?

Rotella? WTF?

I will make you think.
