hey everyone,

finally got my 240 but it has the infamous 3rd gear grind. i went to 2 mechanics reccommended by my peers. i thought it was the synchro and turned out it was. my question to all of you is, do you think it is ok to keep grinding until i get a new transmission? It grinds at any RPM over 3K. but doesnt grind under and when i granny shift. you think i should just have fun with my transmission, because since i've had it i cant have any fun in 2nd gear!

thanx for reading-Nick

ps. changed transmission fluid with 75w90 already

Probably change the fluid to a synthetic would help a tad bit, also try a heavy weight gear fluid such as 90w-140 or something. If you already tried that, Nevermind... as for new transmission, that probably will be the cheapest route.

Junkyard transmission. You can get one under 50K miles for around $300 usually. Any year 240's five speed will work just fine.

redline 2nd gear, skip to 4th gear. Repeat that process till you fix your transmission. My red 240 will 3rd gear grind, and my grey one doesnt grind but shifts funky a lot of the time. I could really use a front clip or two....

i was told that i can only use a 96 or up transmission because they have OBD-II. i was gonna use black240's transmission but his 95 is OBD-I

wat do you guys think of 80,000mi transmission for $250?

What a great idea why didn't I think of that:rolleyes. Sure cuz your third gear synchro is worn, might as well wear the fourth gear synchro down as well, while wasting gas, possibly burning your clutch, and/or causing damage to the engine. Nice suggestion buddy.

How is it going to wear anything going from 2nd to 4th? As long as you shift properly. going to redline isnt always a good idea but you can go 1st to 4th if you really want to, just rev match while you shift.
