I have been at this all gd day and its now 12 am, i have been trying to get this trans on however it doesnt want to get on. I have it to the point where the dowl pins are just touching the block but cant get it any further. I have always been told not to pull the trans together with the bolts but this seems like theres no other way, anyone else have this problem. I know ive done a few transaxles and they have all been tough to align however this is ridiculous.
i was having that problem, so i had someone put a jack underneath the transmission and hold the trann in place while 2 of us on top lined it up the best we can and put the transmission mounting bolts in and kinda used that as a way of aligning it. just make sure not to cross thread the holes.
as long as u konw that the mainshaft is in the clutch disc properly, and not crooked some how, u can use the bolts.
if ur using the bolts, i woudl go aroudn a few turns at a time on each bolt, just to be safe, instead of tightening one bolt at a time completely that is.

One way to check to see if the mainshaft is on the disc properly is to rotate the crank pully a bit. You should be able to hear the transmissions mainshaft rotating. If it doesnt rotate or bids up, stop right there. Dont look for the driveshaft input area of the tranny for rotation as it will not rotate because the tranny should be in neutral.
That's probably not going to be enough assurance.. If you have the mainshaft jammed against the clutch with the splines misaligned, that would probably be enough friction to cause the mainshaft to turn as you turned the crankshaft. It doesn't take much effort to turn the mainshaft if the trans is in neutral. You can easily do it by hand.

Once you get the transmission close enough to engage some bolts, the mainshaft should be properly aligned and inserted into the clutch hub. At least, I've never had a problem with the 20+ Prelude transmission R&R's I've done.

yes its easily close enough to catch a good amount of the bolt. I can hear the trans when i spin the crank but its not too loud bearly audible. I actually put it in 1st gear and then went to neuatral to see if i felt a difference in resistance to make sure i was in there.
Just takes a little messing around and it should slide right in. When I put trannies back on, I try and get it on as far as I can, then use a bolt along with my transmission jack to help keep it in place. One in the front and one in the back and slowly screw them in.
waht position are u in when trying to press it together, i mean ur body physically.
i find the best way to press that final bit together is, to get under the tranny, a kinda like bench press it up and towards the engine. wiggle it helps too, its just cuz the fit is such a tight fit, so u cant be croocked at all.
bad description, buts the only way i found enough leverage/strength to get it in.
i am not sure how safe that is w/o supporting the tranny with atleast a hoist, i'd hate ahve it fall on me, hehe. but i usually hang the tranny from a cherry picker at least, so worst case it is slips alittle, and doesnt fall on top of me and kill me
good luck!

have you tried using a longer bolt to get it in. i always used one of the longer one like the one on the bottom of the starter to get it in then switch it with the right ones.

i double checked the clutch disc and the splines line up but its a very tight fit. Without the clutch and pressure plate the trans slides right on and bolts up fine.
So its a matter of aligning the clutch disc and input shaft i think.

i had the alignment tool centered correctly. Its a very tight squeeze to get that sucker on the splines on the input shaft by hand let alone with the trans. However i guess its possible i may have been slightly off. Ill be trying again in a few.
I remember the first time i did my tranny. It was the biggest pain in the ***. The ATTS didnt make it any easier. I did the whole thing all by my self too, what a bitch. Ever since then i just remove the entire motor when ever i needed to remove the tranny. A bit more work but way easier. I feel your pain. Good luck.
if the shaft is straight, there is no reason it shouldnt slide right in. theres nothing in its way, and if the two dowels are lined up, it'll mate up. ive only changed 2 clutches on a lude, but in my experience if it doesnt slide in, i raise the tranny jack up a little more, and watch it pull together.

i have the trans on a comealong on the boom of the hoist and the block sitting flat on two pieces of wood layed across the legs of the hoist with all the weight still on the hoist but using the wood to make it perfectly straight. So im going in straight i believe but im like 1/8 inch out and im scared that im not lining up correctly with the splines because its an extremely tight fit to begin with. I really dont know what to do ive been at this for atleast 6-7 hours min. and tried pretty much everything you guys said and everything i can think of.
