Hey, anyone have any idea if I the b16 transmission housing would work paired up with a GSR housing? Mines all sorts of effed up and I have a friend with a spare b16 tranny sitting around

 

you should be ok, the only difference is whats insde.

 

That's what I'm hoping for, I think I'm the only person to ever exhaust the use of JB Weld

 

Anyone else? Know of any major differences between the casings of the ls and gsr or the b16 and gsr transmissions?

 

im pretty sure all b-series trannys bolt up.

 

I've got a combination of GSR/ITR/LS guts in an LS case, the only difference in B-series tranny cases is cable vs. hydro.

 

so then i could buy an LS housing and replace my current GSR housing with that? Ive had someone tell me that they are all different and that this wouldnt be possible, hence why im really trying to drive the point home, I dont wanna waste $$

 

Shouldn't be any difference most/all B series would work..i had a B20z with a b16 tranny it bolted up fine..so u should be okay.

 

no

na, i had a friend use it to plug a hole where the stock diff **** the bed and spit pieces.

no, i believe you

however the b16 and gsr/itr bearings are different. i can't remember the exact combo.

mistabone is member here, haven't seen him in a while. but IIRC he is the resident walking transmission library.

 

the tranny i have is fully functional, so it isnt like im mismatching and swapping stuff in to make one working tranny, I have a friend with a tranny from a 99 si and its sittin around doing nothing, I know that it has to be re-shimmed to ensure proper fitment and transmission longevity. I can swap everything from my current gsr tranny over, its all interchangeable as far as I know. so we will see how this goes

 

Mine is "sealed" with JB Weld where the housing is cracked at the drain plug. Unfortunately, it still has a slow leak and like you I need to either replace my housing (been thinking the same thing about a GSR housing), attempt to have the crack welded shut (least expensive solution), or shell out $$$ for another tranny with a LSD.

 

yeah i think you may run into problems with different size diff carrier bearings.

if you do, autozone bearings all day.

do it

 

All the Hydro B-series trans cases are the exact same with one exception..

The NON-LSD cases have aluminum fins that direct splashed oil to the spider gears in the differential. The LSD case has these fins cropped to make room for the larger factory LSD unit. I've used Non LSD cases for LSD diff transmission builds and trimmed the fins using a pair of wire dikes or pneumatic angle grinder. After a wash in the solvent tank they're good as ever..

What I would NOT recommend doing is mixing case halves.. Tranny halfs between years vary location ever so slightly, but can use all the same parts. I accidentally used a late model case half(ones that have vin numbers and small diameter vent tube) with an early case half (one with no vin numbers and large diameter vent tube) and it worked, but I had problems shifting gears as it kinda binded things up with the shift selector/forks.. So if you have good internals, put them in your buddy's case and be done with it.. If you need any help or parts, the guys at Gearspeed.com are VERY good guys to be friends with.

One thing you WILL need to know, is how to shim your differential.. If you have too much end play or not enough you can kinda mess things up... The shims honda uses are referenced by internal hole diameter and thickness.. And I'd recommend replacing ALL seals if you're going to do all that since you already have it out..

Hope this helps you out..

 

thats what the plan now is, we are just going to use my internals in his b16 housing, then throw his b16 internals into my old housing and sell it cheap. my buddy is a pretty knowledgeable honda person and hes a machinist so hopefully this will be up and running this weekend

 

Did you ever get the internals swapper??? The reason i am asking is because i have almost the same problem you do just in reverse. I have a good b16 trans with a bad case and a bad ls tans with a good case. A lot of the information I have found is some people saying you can and some people saying you can't but have not been able to find anyone that has actually done it… Any Info will help… THanks in advance

 

The cases are basically all the same. Some have a larger vent tube than others but that's it. What you have available to you will absolutely work. Just make sure you shim the diff and mainshaft when you swap them over.
