Tranny work tips - Honda Prelude Forum

For anyone that's doing any type of transmission work, I would HIGHLY suggest that you stock up on the bolts that hold the tranny housing and clutch housing together.

The first time I installed my LSD in my 5Gen, I stretched 3 of the 12 smaller bolts that hold the two housings together. They had been torqued to spec only 3 or 4 times to check the preload on the differential. They stretched when I was doing the final assembly on the tranny. 2 of the 3 were obviously stretched. I had stretched the threaded portion a good 2 or 3mm. After stretching 3 of the, I bought a complete new set of bolts.

Today, while assembling my tranny, I only torqued the bolts to 15 lb*ft to check preload on the diff. I had to do this twice. Then during final assembly I had one bolt stretch. The torque spec is 20 lb*ft, so I didn't even torque them to spec to check the preload, so I thought I would be okay. So, these bolts have been torqued to spec twice, and torqued to 75% of spec twice, and I still had one bolt stretch.

I don't plan to replace all of the bolts this time, I am just going to replace the stretched one, but if you're planning on doing this work, I would replace all of them. They only cost $1 or so each, and there are 12 of them.

Also, make sure the counter shaft c-clip is fully seated before you reassemble the tranny. I didn't have a problem with this when I did the LSD install, but for some reason, the c-clip wasn't fully seated, and I couldn't get the c-clip around the bearing. I ended up having to take the tranny apart again to seat the c-clip.

One last thing, installing the counter shaft, main shaft, and 3 shift forks into the tranny by yourself is a PITA.

It helps to have a person help to hold the shift forks in place.

Sorry guys, no pictures. I have some pictures from the LSD install, but I was more interested in getting work done. Not to mention I had Honda tranny fluid all over my gloves.

good to know. i actually didn't stretch all but two bolts on mine which held the bracket for chassis ground.

the thing that had me on assembly for awhile was the washer adjacent to the c-clip. it sits atop the bearing and is supposed to sit in a groove in the casing. it has a 90 degree extension to it. that was a PITA. i was using gobs of vaseline to get it to stick there, but then problems with the shift forks took me too long and the washer moved around. did you have any problems with that washer or no? have a better way to do it? cause i do plan on getting the quaife later on...would be nice to know an easier way.

The Helm's shows the correct orientation of this washer (or whatever it's called). I positioned it like what was shown in the Helm's and I had no problem.
