f22b2 AT replace to MPJA AT
Recently bought a transmission offline to have a newer tans in the car. Suprisingly the stock tranny has lasted 260k..with some sort of patch work on the outside/bell housing if my terminology is correct but none the less time for a newr one. I know im going to have to reple the shift linkage cable because it was cut, also the harness to the tranny itsself was also cut. Im unsure if the torque converter from my old trans qith work in the mpja tranny and im unsure what the stock one is..but if anyone could give me some advice or two cents even id appreciate it.
The MPJA will work in a '90-97 accord no problem. It is the same externally as the 90-93 and 94-97 ATs. Reuse the throttle valve cable and shifter cable from your Accord. Do not cut anything. Reuse the throttle valve cable bracekt from the accord asa the MPJA is from the Odyessey and is incorrect for the accord. Take out your old transmission and transfer over all bracketry from the Accord to the Ody trans.
There are two major differences. One is that the Torque Converter in the Ody is of a larger diameter and you will need to use the drive(flex)plate from the Ody. Never swap TCs between used transmissions.
Two the MPJA was beind used in the Ody Van has a lower gears. Thus your tachometer will read higher due to the lower final drive. Accord is ~2700 @ 72, Ody will be closer to 3200rpm.
Enjoy your new found acceleration.

Wow i didnt think anyone knew anything thanks alot! So just reuse the trans bracktry and my old tc? Or get a new one? And the flex plate from the ody right? Once again thank you for your input.
Yup. When you pull out your old trans compare it to the new one, note the differences in any brackets. I think there are two brackets that need to be transfered over to the MPJA and one on the MPJA that just gets removed. While you have the MPJA on the ground on the right side cover there are two sensors called NM/NC, with a 10mm socket remove the bolt and pull them out. They are magnetic pickups that let the PCM/TCU know what the shaft speeds are allowing for correct shifting. If they are covered in ferrous material the resolution of the signal will be lost and erratic shifting will occur.
Leave the TC with the transmission, leave the MPJA TC on the MPJA transmission. If it is the larger diameter TC,than the accord, you will need to locate a properly sized driveplate. Whomever sold you the trans should have given you a driveplate(honda terminology) to go with it.
I'm fairly positive it is the same diameter. I think I've seen F23 driveplates as the same diameter. But you will have to pull the transmission and verify if the TC diameters are different. You will want to measure the bolt circle diameter.
It will be fairly obvious when looking at the TCs through the starter hole.

You could reuse your old TC but two things I would do. One is to do a good flush on the old transmission before removal. If locally they seal Sea Foam, look for Sea Foam Trans Tune. It is a cleaner and gets rid of varnish build up.
When no more junk comes out then you have removed most of the crud from transmission.
With the old transmission removed take the torque converter to a reputable transmission shop and have them check the freeplay in the stator/clutch lockup inside the TC.
Then you will need to purchase a TC O ring, and a new seal.
I would also recommend replacing the differential seals as they may have been damaged during shipping.
As for the brackets, you will just transfer anything over from your original transmission to the MPJA.
After the MPJA is installed I would do another flush with the Trans Tune fluid.
Remove all the crud and junk that you can from the transmission for a longer life.
