Incorrect, the bellhousing on the manual transmissions can be changed; if you have a 2004-2006 6MT, you can buy a new bellhousing for about $250 (last time I checked); the bellhousing will bolt onto the existing transmission and to the new engine.
If i were to use the 05 manual tranny what bell housing would i need to mate the j37a1?

You'd need a bellhousing from a 2007-2008 TL Type-S 6MT. That said, it isn't a trivial operation to swap the bellhousing out; you might want to consider just sourcing an entire 2007-2008 transmission.
Good luck finding a reasonable priced 07-08 6mt trans. I'd like to get one for my RL block. Prob be easier to just get the j37a1 crank, rods and reuse your block and trans
There is also a difference between the two, cast aluminum front engine / transmission mount brackets.

There are four, M10x1.25 bolts, 30mm long that fasten this bracket to the engine/transmission.
2 bolts thread into the engine.
2 bolts thread into the transmission.
The 'old' (03-07 Accord / 04-06 TL) bracket is not flush. The bottom, transmission bolt mating surface sits further inboard / closer to the transmission by a few mm. On the 2007-2008 TL Type S 6MT bracket, all four of the bolt mating surfaces are the same depth (as in, the bracket sits completely flat on my work bench). I had hoped that using mere washers between the bracket, and the engine/transmission for the 3 bolts that are different depth would set the bracket at the same location as a TL-S 6MT bracket would, however that is not the case. You would have to sand or grind down the offset surface so that it sits even with the other 3. Unfortunately, there is not enough material where this would be feasible.
If you have OEM style engine mounts, I'm sure you can get away with placing washers between the bracket and the engine/transmission anyway. If you are using harder/solid mounts you'll likely want to get the TLS bracket.
It is possible that the 2008-2017 Accord Bracket might work. It will fit the engine/transmission, however I have never seen one in person so I am not sure if it will line up with 3g TL / 7g Accord Front engine mount.

J37a1 uses the "revised" bellhousingpattern similar to j35a8 in the 07-08 type s. Therefore 04-06 TL needs either a 07-08 type s 6mt transmission (lsd) or a 2008-2014 accord 3.5L 6mt trans (non lsd)
The starter is different on the new 3.5 6mt trans, and you can not reuse your 04 TL 3.2 6mt starter. Go with the corresponding starter for the trans your using. Do not use the 3.2 flywheel use the same corresponding year flywheel as the starter and trans. For example i used a j37a1 and 13 accord 6mt trans in my 04 TL. My TL 6mt starter would not fit i had to also buy a 13 accord 6mt starter and 13 accord flywheel to bolt to the j37a1. You can reuse your stock pressure plate as the 3.2 clutch components bolt to the 13 accord 3.5 flywheel. You can reuse your 6mt flywheel bolts.
The injectors, coolant temp sensor, and oil pressure clips will be different then the ones on the TL harness. Depin the injector and oil pressure clips and swap them with the j37a1 clips for easy plug and play of the engine. On the 13 accord trans the 2 vss sensors were different, swap them with the speed sensors off your 3.2 6mt trans to plug them in with the stock harness..Everything else such as crank position, ignition coils, knock sensor, cam sensors, egr, iat, TB, etc will be plug and play.
Fuel line connection is positioned different then on the 3.2, however stock line seem to be able to be ran without having any hard angles, i dont advise swapping fuel rails, injectors, and fuel line connections from the stock 3.2 for ease of install, because the smaller injectors will run the 3.7 too lean. So depinning and swapping clips to accommodate the j37 injectors is worth it on the stock 3.2 harness.
My j37a1 came without the mount brackets, so i noticed when trying to move over the mount brackets from my 3.2 that the front mount bracket does not fit flush onto the j37a1 and 13 accord 6mt. I used 2 washers to allow everything to sit flush and mount flat.
My 3.2 PCDs were able to work perfectly on the j37a1aswell as the rest of the exhaust. Trans upper and lower mounts all lined up perfectly on the 13 accord 6mt and j37a1besides the front bracket needing washers. The Stock 3.2 shift cables and bracket fit like they did on the stock 3.2 trans, aswellas the slave cylinder. Stock axles fit the 13 accord trans like they we're suppose to.
My stock alternator and power steering pump and ac compressorbolted directly to the j37a1.
The Coolant temp sensor on the water neck of the j37a1should be swapped out with the sensor off the stock 3.2 to be easily plugged in with the stock harness.
I test fired the j37a1 on the stock 3.2 ecu and it ran, and idled perfect, with no CEL. Hondata is obviously recommended.
Wire up for hondata and and get a 07-08 TLsecu programmed to the car.

Hey guys im back! The car is literally still on the road first of all. And i have been keeping her on redline since it was built...now, on to the solid mounts not being able to be used is false. I'll go out and take a picture right now if I have to. I've had billet mounts on my setup since day one, and it is still currently that way right now sooooo.... but thanks for the clarification I'll have to play with some brackets when I ever decide to get in there, but you know what they say, if it ain't broke don't fix it and she's still ripping so ill leave my 04 trans bracket and innovative 85a solid mounts right where they are 😁
