Ok fellas tonight and the last three nights I have rebuilt a P2A5 for an accord, another M2B4 other than my POS, and a H2U5 out of a 90 accord. After taking pictures and combining measurements along with gearspeedinc.coms advise on casings and gears and whats compatible and whats not along with the post of the trans gear rebuilds on this site I have successfully rebuilt 3 trans. Also thanks to Mista Bone for some American muscle help of tapping the trans upside down for the snap ring.
So afer taking that data and the advise I figure I can use the M2B4 LSD and the casing and use the P2A5 gears that are longer for boost friendly happyness . Post up and see if it can be done or if you think so or NOT. I have nothin to loose since my 5th and reverse went out on the M2B4 but I got a fresh P2A5 with 21,000 miles on it out of a junk yard today for $300. Yeah it will mount up and be fine but NO LSD.

Help and advise are welcome.
---- YOU JD hahaha just joking

 

this a Lude tranny, H22?

LSD case is different.

 

Yeah if I understand you right. Lude LSD case and lsd are staying the same. I'm putting the gears out off the P2A5 accord into the M2B4 case. So long gears and LSD. I still need to measure the shafts height and diameter at work since they have large calipers,indicators and a granite block to make sure its flat.

 

VICTORY


I got it to work and spin freely, still had an issue with the retaining ring but I held it upside down and beat it on a wooden block 8 time than CLICK

I had to only put in new bearings and 5th reverse fork and the shift mech out of the P2A5 cause the gear selector was burred up from trying to force it into reverse all the time with the original M2B4.

So Cliff notes

Sober night
Swapped out long gears into a short geared LSD trans
Replace the nesseary bearing

Going to install SOON.

 

I rode in a kids car that had an H22 w/t3/t4 tuned professionally. He thought his P2A5 trans. was a JDM H22 trans w/LSD>. With the P2A5 he was running low 14's in the 1/4 passing through the traps in 3rd gear. It didn't seem that anything else could have been wrong with his setup besides the Accord DX trans. Maybe with your higher power levels it won't be as bad.

 

low 14's on a boosted setup with an h22? WTF?

Low 14's can almost be had with an i/h/e h22 w/h22 trans in a damn accord!


Widebody,

Which gears did you swap?

SO let me get this straight,

M2B4 casing(with the LSD unit)
P2A5 gears?(which accord engine does it come mated to originally?)

This is awesome news.

 

94-97 Accord Dx Lx= P2A5

Yeah those gears in the M2B4 casing with the Lsd M2B4 LSD

you have to use the casing for the M2B4 cause the Diff is thicker

 

can you mix and match or do you have to use one trans gears?

 

I'm sure you can mix and match, GEARSPEEDINC.com does. When you do you have to make sure you press the new "AKA" used gears into place. they have to be at spec and not just a hand press do it your self. I tried tonight for an extra trans with the M2B4 with the H2U5 5th gear. Again I stress SPECS. Get a actual honda SPEC rebuild guide and make sure the main and the counter shafts gears match to the TEE. If not you have failure quickl. SCRATCH SCRATCH whats that......................OH ---- I DIDNT MEASURE

 

2/3rdsfor kiill myself GREAT yeah

I bet you not that I'm going to get the click for a F and H series rebuild.
