Manual Tranny Swap

Jason have you looked into just buying a manual and selling your auto?
Well, here's the story...
Last fall my tranny started to slip when it is cold. After a lot of research on Honda-tech, it sounds like this is very common in 6th gen Accords caused by degrading clutch packs leading to a clogged filter (which is not accessible with out taking apart the tranny). Before I proceed with any rash decisions, I'm gonna have a diagnosis of the problem done somewhere here in town to see just what the problem(s) actually is(are).
So it looks like my options may be: fix this auto tranny, buy a new auto tranny, or swap to a 5 speed. Apparently, fixing this tranny will cost a shit load of money ($1.5-$2k according to honda-tech) and buying a new one will cost even more( honda-tech says upwords of $2.5-$3k). If the difference in price is not too drastic between sticking with an auto or swapping out to a manual, I see no reason why I shouldn't go with a 5-speed, especially considering that replacing one 6th gen auto tranny with another still leaves the risk of the new tranny taking a dump on me (they were all pretty much junk). Apparently, f22, f23, h22, and h23 trannies can all be applied to this swap, with none having anywhere near the problems of the f23 auto tranny.
So as you can see, unfortunately it's a little more complicated than just selling this car for another one...
Has anyone on Fargostreet had an auto to manual swap done? -
If you remember "spoolude" I did an auto->manual trans. swap in that thing when the H22 went into it.
Tufte did one in Chuck's old prelude. Roadsounds did one in a 4 door civic not long after I quit, Dave did one in his NA-T, I've done older crxs/integras.

I've done a couple.
You can find either a auto or manual trans for your Accord for under $1000 w/ around 50-60k or so on it.
Im not pushing you away from a 5 spd swap @ all but i guarntee you will have A LOT more $$ into it all said and done. If your doing it cuz you got plans to maybe turbo or something big and are looking for the extra strength, then go for it. If your doing it just because your auto trans is going out and you just want a daily driver i'd just replace the auto.
Even if you bought some of the most expensice auto trans i saw which were around $1500-1600 + anywhere from 8-10 hours of labor depending the options on your vehicle your gonna have right around $2000 into it.
5spd swap trans were going anywhere from $600-1400 depending on mileage. You will need to purchase a clutch pedal assembly, shifter assembly, linkages, master cylinder, slave cylinder, clutch, flywheel, hydraulic lines, axles etc.. You can nmow figure in that 8-10 hours to remove your auto/trq converter, etc, and replace it w/ that manual/clutch/flywheel. 1 hour labor for the master cylinder, 1 hour for the slave cylinder, 1 hour to run the hydrualic lines, 1.5 hours for the clutch pedal assembly/clutch switch, 2 hours for shifter assmebly and linkages. Now figure in the parts cost for whats listed above. This should give you a rough idea for a cost comparison for doing the swap to replacing w/ another auto.

I had the tranny in my 88 prelude swapped from auto to manual by Type-R about 5 years ago, so yes, people on here have had it done.
I have also had my auto tranny built for about $1500 by Aamco and I have also had the high stall TC done by ProTorque. Depending on your reasoning for doing the swap (racing?) you might be better off doing a rebuild of the stock tranny w/ modified valvebodies and a high stall Torque Converter.

assuming you yourself could do it, congrats. your probably the only person on fargostreet who can rebuild a tranny(correctly).

Depending on your level of mechanical ability, I would guess that you could handle doing either of the swaps yourself. Replacing the auto at least would not be very difficult at all. They mostly just take time. It is too bad i didn't know about this earlier because i had a friend with a 5 spd accord that he was parting out and the motor was sold so he had everything for a manual and i would guess he would have sold it for under a grand for everything. But im pretty sure it is all gone now.

IF there are parts that are difficult to find for the swap...wouldnt certain prelude parts bolt right up??
I don't think there are too many rare parts at all. Everything seems to be readily available.
I wouldn't even consider touching a tranny myself. -
i did/ am doing auto to 5-speed conversion. the hardest part is finding all off the parts.
you also could need differant cross members, brake pedal or assembly depending on how it is on the vehicle, shifter, shift boots, center counsel.
i have been buying parts when i see them for sale for over a year and on the last couple i am resorting to buying new. i didnt really have a set time i needed them so ive just been picking them when i see them and the motor is going back in in the next couple weeks so i just ordered new parts.

Geez... there sure is some drama in this thread. I say if you have the time and a place, try to do it yourself. I have done plenty of auto to manual swaps and manual to auto swaps over the years. If you can find all the parts its fairly easy depending on the car. I am not fimiliar with your car really, but doing the swap should be just all mechanical parts, I don't think the wiring will matter, but I have run into cars that have to use a wiring harness for a manual car. Either way if you figure out what your doing, and need help or someone to do it for you, I am always up for a challenge. If you go with a new automatic, I could probally throw it in fairly reasonable too.
