B18 S80 tranny only third and fourth gears
I had to split the tranny apart about a half inch to get out a piece of metal that fell in the tranny. The piece is out. But I fear I may have bent something or damaged something whilst prying it apart an extra 1/8th inch to get the price of metal out. Any ideas what in the tranny may be causing this behavior ?
the piece of metal was from my transmission filler tube. Never ran the tranny I was installing a clutch and just adding some fluid back in when that piece fell in. So no it was never ran with metal in it.

I took it apart. I don’t see anything wrong that sticks out. Is it possible that I made the mistake of not seating the case properly. Possibly binding things up. It’s shifts fine worth the case off now.

😂thanks. Yeah it’s apart. I’m guessing it didn’t aligned back up right. I didn’t think only taking off that far would miss align the tab. But that must be it. I just wondered if this is consistent with the main shaft tab not being aligned.

Ok so I believe the orginal problem was the snap was not all the way set. And the trick to seating the case back on is one make sure everhing is in neutral. Two make shift selector rod is all the way seated and. Third was making sure the back of the snap ring was picked to the back. So once the bearing had pressure on it. You could just open the face and pull the bearing up with needle nose. , avoiding flipping it over. Should be all good now as long as the new outer case is good. This one is cracked, I’m am concerned in weld want hold in the long term.

Swapping the case requires additional testing and modifying of clearances between the differential, mainshaft and the case. If the crack is not in a really bad spot, you might reconsider the welding idea instead of adding more issues to your situation.

Unfortunately it’s on the bottom of the snap ring nut. So when it’s torque it’s makes the crack a little bigger. I got another case labeled a s80. Same as what I have.

The case number may be the same, but it isn't that simple. It sounds like you are relatively new with transmission repair, so I would suggest you find professional assistance with the case swap. It requires specialized tools and parts that you may not have.

Re: B18 S80 tranny only third and fourth gears
Everything I’m reading says the cases swap over no problem. What tools ? Or parts are you referring too ? This is first time in a b series transmission.

Re: B18 S80 tranny only third and fourth gears
Everything I’m reading says the cases swap over no problem. There's the inter-web... and then there is real life. The case CAN be swapped... but it isn't like changing shirts. Both the differential and main shaft clearance will almost certainly change, so you will need to be able to measure these clearances. A factory service manual will show what the limits are. What tools ? A feeler gauge for the differential, snap-ring pliers for counter-shaft, and a specialized main shaft fixture (expensive and a special order part from the dealership) with a dial gauge to measure the main shaft clearance... which you will see in the factory service manual. Or parts are you referring too ? Shims for both the differential and the main shaft. This is first time in a b series transmission. Obviously, because you are ill prepared for the job you are attempting. I am not trying to discourage you here, I am attempting to get you better prepared. Understanding what you need to do and how it is properly done allows you to make the appropriate decision to press on or seek professional help.
Keep in mind I am only changing th me out case. Not even takin out the shafts. I know... it looks easy, but it is far more technical than it appears. You can try it your way... and you might just get lucky doing it as some lucky schlep did that you read about on the net... but when you blow the side of the case out because the differential was too tight... or it won't go into gears because the main shaft free-play is too tight/loose... you know that the idiot who said it was easy didn't tell the whole story.

Thrust play 1000-4000. I have all those tools. This guy used a dial gauge for the thrust. Be had no mention of the main and counter shafts for play
much respect for the info. I refuse to have others work on my car as I had a simple alignment done and they didn’t tighten the tie rod and I lost steering at 80 on the way home. This isn’t rocket science. It’s just a Honda parts and tools are cheap. I have built supras and many other cars. Just never inside a b series or trannies that much in general just a few shift kits for a 4l80 I put in c10. My first swap was into my 92 eg b16 back in 2000 when I was still in high school. Just finally back into Honda’s where it all started. I have no problem taking the time learning and doing it right.
Again I appreciate your help and input.
