Hello i traded my non LSD transmission for M2b4 trans and installed.
Now i have issue when i am turning on low speed
i.e. When I am turning right, left wheel is blocked and starts jumping :D
It works fine on high speed.

I will change oil i don`t even know what is in now, but anyone had issues like this?

please help me i must replace this issue before 12th of may...

 

sounds like you have the tranny in a civic and have it lowered to much . lsd h trannys will bind in civics when lowered to much. whats the tranny in and what axles are you using?

 

Tranny is m2b4 axles are from yonaka and now with some custom mods (short passenger side). trannys Old owner told me it was doing same in his bb4. I think ihave problem with diff. Or maybe oil change will help.

 

If its a problem with the diff then a oil change isnt going to help. sounds like diff has got hot before , ran low on oil probably.

 

Its a NON clutch LSD... Somethings going on with the binding.

 

Evrry m2b4 I've pulled apart was clutch type.

 

Wrong. NONE of the M2B4s you pulled apart were a clutch type.

 

Vicious type.. I pulled apart a m2b4 with a helical lsd once..lol still have it..

 

I have a few in the shop. I'll look at them. never really paid much attention but surely thought they vicious type. my t2t4 tranny is helical and it's different from the m2b4

 

Hello Guys thank you for response.
so I found 2 damaged M2b4, one of them does not have 1 and 2 gear and second does not have 3 and 4 gear both are with good LSD diff
I will part out those and mine too... I think I can build one good trans for me

If you are interested i can take pictures of diff on 3 M2b4-s

I missed drag racing in 12-th of may I am so angry but its ok i will go for it in future
If you are interested K20 Civic won in 3 classes I was So happy ... and proud
A class 0-cc to 2500cc (RWD+FWD)
B class 2500cc to 3500cc (RWD+FWD)
C class 3500cc - 4400cc (RWD+FWD)

 

m2b4 is not a clutch type lsd. i have a m2a4 and a m2b4 and i know for a fact m2b4 is not a clutch type.

 

You MUST use the M2B4 cases for the M2B4 diff. Its wider. IT will NOT work in any other case.

Ive built broken and rebuilt more H22 trannys than ANYONE you know. Trust e... ALLLLLL different kinds of itterations and frankensteins looking for one that worked to hold my power level... I went through over 25 in my car alone, not counting all the trans Ivew built for people and the latest R&D of my current gearset/box

Seen ALL Of them, and know what works and doesn't. Know which diffs are what, and the B4 is NOT clutch. Period

You CAN shim the B4 case to put a normal sized diff (LSD OR NON) in it, but its dumb.

x2 I got a spare 30k m2b4 with no case... for a few pennys...case was cracked and he didn't have b4 around... clutch housing was fine... good for spare parts and my other b4.

 

I know a guy looking for 1 diff bolt lol

 

Thats me Spiker!! Thanks for remembering me..lol.. I need one diff bolt!!

Hey, I am in desperate need of an M2B4 Tranny ring gear bolt that bolts the LSD to the ring gear...there are 14 of them, 10mm heads, normal threads, not reverse threads like the other differentials in other hondas....Can I buy a bolt of you from one of your scrapped ones?? I will pay you no sweat...
PLEASEEEEEEEEEEEEE....what do you want for one????

 

John help this guy out
