I picked up a TII tranny yesterday, first one I've had now, but the guy didnt know if it was from an S4 or S5. It was a part pulled from a guy's son who owned an RX-7 six or seven years ago and was sitting in his garage. So, what's the best way to physically ID the differences? I tried to search but could not find exactly what I was looking for.

 

ask the guy what year it was 86-88=s4 89-92=s5

other than that i'm not too sure that there are tha many differances betwenn the 2

 

I did, but he had noooo clue, and his son is in Iraq currently and isnt able to get ahold of him for a bit.

 

ask him about idenitfying marks on the car such as the s5 has round tailights the s4 are line designs and the trim the dercoration groove thing is at an offset towards the top if its an s4 its in the middle on s5's

 

The number of veins on the transmission case will tell you. Post a picture of it and I can tell you in 2 seconds.

 

Ditto to evileagle. Gotta love vins on parts

 

I thought he meant "veins", like the ribs on the transmission casing.

 

That is exactly what I meant. I didn't mean VINs

 

Whoops :P ither or works as long as you can identify it :P

 

I'd like to see you guys ID one of those "smooth case" turbo trannys.

Who cares...
As long it has the 1" x 23 input shaft, you're good to go.
If you really insist on ID'ing the trans, just spin the input shaft and count the # of rotations on the opposite side when shifted into 5th gear...

Heh, true. Though really, the odds of someone actually getting one of those is pretty slim.

 

I would assume you could tell from the mount. I believe an S4 mount won't fit on an S5, and likewise the other way. So if your old one is an S4, see if it fits on the new tranny. If it does, then it's an S4, if it doesn't it's an S5.

I cant access my photobucket here with me right now but here's a link so you can at least see the pics from the craigslist spot I got it from.

until it turns out to be an older R tranny from a B series truck...

 

Anything else?

 

Here's the pix from that link.


Looks like an S4 TII trans to me. Anyone else?
