its a 95 accord EX VTEC automatic. i know that other year trannys can be used but i dont know what needs to be modded to make them work. i heard i had to change TCMs for certain years. can someone tell me exactly what trannys will fit with what mods, since searching is disabled?

thanx

 

As far as I can tell 95' to 97' Accords EX and trans code is MPZA.

 

Well, if Honda part numbers are any indication; it breaks down this way.
90-93 Accord Automatics
94-97 Accord Automatics
They all fit the F22 family of engines.

From this you can infer that any transmission from '94 thru '97 will fit (and plug in) without incident.
Most likely the '90-'93 series will fit as well, but there may be reason (other than a part number supersession) why the case PN# changed.

The differences in Model number (MPZA etc and others) refer to final drive and internal gear ratio's (If any).

ok....so now i gotta find somewhere that has the differant gear ratios so i can see if a non-vtec trans will be worth it, or if ill never see vtec. no one posts specs on auto trannys.

 

There is no such thing as a non VTEC or VTEC automatic transmission. All of the 5th gen automatic gearboxes have the same gear ratios. It's the TCM that determines the shift points.

94-97 F22B1 & 2 AT gear ratios

1st - 2.736
2nd - 1.484
3rd - 1.026
4th - 0.674
Reverse - 2.047
Final Reduction - 4.133

90-93 F22A1
1st - 2.7.5
2nd - 1.482
3rd - 1.028
4th - 0.707
Reverse - 2.047
Final Reduction Gear - 4.285

 

you can also use any h22 auto tranny..alot of motor malls have alot of auto trans laying around cuz everyone wants a stick

 

alright cool.

thanx everyone.

 

The H22 may fit, but I believe it has steeper gearing and final drive ratio.
Good for acceleration, but hidious for highway cruising.

^x2

IIRC you would have to get the Prelude TCM to go with the H22 trans. I'm pretty sure that the H22 trans would work like pooh with an Accord TCM.

If you do look into an H trans, add these to the A/T gearing list above.

H22A1
1st - 2.528
2nd - 1.427
3rd - 0.976
4th- 0.653
Reverse - 1.863
Final Reduction Gear - 4.785

H23A1
1st - 2.705
2nd - 1.535
3rd - 1.057
4th- 0.750
Reverse - 2.047
Final Reduction Gear - 4.428

 

thanx for the info everyone....BTW where did you get those gear ratio specs from? i might be needing more for my other car.

 

Verbatim from the Honda shop manuals that I own.

I only have manuals for the following: (+ toss in a pinch of EDM & JDM info)
88-00 Civic
93-01 Prelude
90-97 Accord
