Graunching in third!!

[Guest]

What else can cause a box to crunch in third gear if the box meant to be an excellent runner?

I cant change straight from second to third i have to let engine revs go down before it goes in without crunch same for the chopping down change also 4th to 3rd

just wandering if it could be selectors arms since i have to use parts of the old and new one that came with the box

Anyone have had any problems with third without being an internal issues???

[Guest]

sounds like it isnt an excellent runner, sounds kinda syncro

-smurff

[Guest]

Yea i am thinking same also.... just hoping its not... but its pissing me off since the guy bullshited me and i hate bullshitters!!! I just wanna see what i can do first before i give that guy a ring and demand answers lol

[Guest]

TM was it?

Possibly synchro. Try sticking some new/different oil in it. Mightve been fine with the oil he was running so i wouldnt start yelling just yet.

[Guest]

whats the best oil to use? its from a 96 wrx but the box is in a first gen legacy

[Guest keltik]

Everyone will reccomend something different.

Personally ive used Valvoline 75w-90 and in another car ive seen just straight ATF used. Both shifted fine.

[Guest boostin]

Yup Hondas use engine oil, Mazdas use ATF, Subbies should be 75w/90 or 80w/90 though. Its needed because of the hypoid front diff. Something is better than nothing though eh Keltic.

[Guest keltik]

Meh the oil is overrated. You get a really positive nice snickety snick feel when shifting with no oil

[Guest]

Yep oil is over rated, did f...all to overall improvement. I admit i bought a dud gear box from someone who told him its a good gbox I bet and I am very furious about it ....

Can someone here confirm that shifter arms can cause this problem?? I have to use part of the shifter arm that came with box and my old stay arm and gear lever, not sure if i put the shifter arm the wrong way since i was in a hurry cause of loosing daylight....

but some how syncros comes to mind :-\

[Guest keltik]

If you put the shifter in backwards, 3rd gear requires pushing the lever forwards through the radio

So no, you cant have installed it wrong.

try a double declutch and rev matching on changing,if it works better then it most likely synchros

[kingersman]

get this fixed?

sort of sounds like mine.

had to double clutch or shift slowly with low revs

[Guest]

Na havent fixed it yet, I gonna get the guy i bought it off to fix it or demand some money back but cant do it till i have my other car back on the road.

yea double de clutch or shifting slowly in low revs works fine but pain in the butt tho... if i do a mistake "graunnnccchhh"

[kingersman]

when you try and double clutch it then miss the timing... makes you look like a complete dick ahaha
