my tranny caseing has a big hole in it, i believe that there are two casings, the one closest to the tranny fluid bolt is messed up, are tranny casings interchangeable through b series trannys? i got a USDM type r transmission

 

all hydro cases are the same

 

kool thnks

 

Ok. I'll bite

how did you manage a big hole in your tranny casing?

Yeah, how'd you do that?

 

car accident, the tranny mount smashed into da tranny

 

they are not the same! the diff bearings are different in the b16 and b18. The outer is the same but not the inner

 

o, hmm what are my options?

 

i got tranny case for $150shipped each side

 

no ALL of the casings ARE the same. Depending on the year of the hydro it will have different races for either a open face bearing, or a closed bearing. You can easily pop these races out and put the races in from your old tranny.

The housing though is exactly the same.

I had to change mine a few months ago when the bolts ripped out from the back mount.

 

btw you might want to order the closed bearings for your diff. They are better than the open faced ones and by design are better to stay in specs for clearence.
