I have a 95 F22B1 with the P2U5..I also have a H2A5 that was from a 92' F22A1..would I beable too swap and use the H2A5 with my B1? And if so is there any kind of modifications id have too do?

Yes, probably need to drill and tap the two holes for the mount. But why? Older transmission, more than likely higher miles and no gearing advantage.

its a transmission that I've had for quite a while and my P2U5 lost reverse.I hear it could be a simple linkage issue but im not 100% and when I last ran the H2A5 there was no problems..are you familiar with one that just looses reverse and nothing else..Ive driven it like this for some time with no interference with 1-5

MAD_MIKE would have more insight on the transmission internals, but I believe 5th and Reverse are paired.

I'm more of an automatic transmission geek, but a transmission geek none-the-less.

H/F-Series Transmission Codes & Ratios - Honda Prelude Forum

P2U5- 3.307 -- 1.809 -- 1.185 -- .933 -- .658 -- 3.00 -- 4.062
H2A5- 3.307 -- 1.809 -- 1.185 -- .870 -- .685 -- 3.00 -- 4.062 DX/LX
H2A5- 3.307 -- 1.809 -- 1.230 -- .903 -- .705 -- 3.00 -- 4.062 EX

Pretty close gear ratios.

90-97 Accord transmissions are pretty much the same externally. Just transfer any brackets over to the 'new' transmission.

yes 5th and reverse are..its just odd one day no bang tick pow nothing. never grinded..its like theres something blocking it from going into gear? im no mechanic for sure. I think I know just enough too **** myself.but I wanna eventually know my accord all the way down too the bolts. I really appreciate all the insight and info from all you guys \m/

If 5th and Reverse share the same shift linkage, it may be that a pin or bolt has backed out. Might be lucky and see a problem on the external shift mechanism.
