Transaxle Identification

[Legends21]

I am communicating with a seller of a transaxle. I asked them to tell me the transmission code that the Clark's Garage illustration says is stamped on the bell housing. The seller says that he can not find any markings. Is there another location that the transmission codes were placed?

 

Thanks.

That is the only place as far as I know. Should be on the top of the tranny bell housing. Might need to clean the crap off to see it.

 

Maybe you can send a picture of where they are to help your seller.

Getting in a used tranny with a short 5th if u are still in market.

...and be aware. There are trannies out there now that have been cannabalized of their short 5th gear. You have to make sure it still has the gear pair if that's what you're really after.

I'm bumping this thread because I have a tranny in my garage in which I can't find any code where I expect it on top of the bellhousing. I'm thoroughly confused as it's cleaned up on top and there's no code hiding in any gunk there.

[Tim Comeau]

You have to clean VERY thoroughly on some trannies. If the stamping was light, it might look like the rest of the casting surface texture. Try a bright light at a shallow angle off to the side. The only other Porsche tranny I know of that looks like a 944 is the late 924 turbo. You can tell because it has a 20mm shaft, vice 25mm in the 944. I'm not sure where those are stamped. I'm told the same 944 tranny was put in some Audi's as well.

Do the casting numbers on the side of the tranny say 944?

[wildbill846]

Ok, the plot thickens....where should 944 be cast? I may have to clean some gunk to find that. So far I only find the numbers 016 301 103 cast in the side of the bell housing. I'm still having no luck with the code on top.

924Turbo unit is identical to the early 44. Same input shaft. (It's the early 924 that also is nearly identical but has the smaller input shaft).

Bill, I think the 016 301 103 is the part number for the case casting.

 

ALL the 44 trans are "oh-sixteens". That's just the basic Audi derived unit. Since you've got it laying there, all you really need to know is whether it has a short 5th and/or a LSD. You can tell both by just spinning and counting. Also, if it's an early trans (without the speedometer drive) or late. Or, if there's not speedo drive but it's a short 5th then it's out of a 924S. Which is perfect.

 

I've seen some that either the guy with the hammer was in a pub the night before or the code just wore off.

[wildbill846]

If the code is that light, it is very possible it's been polished off on this one.

 

This is a late tranny and it's an LSD. I want to know if it's got a short fifth. How do I determine that in the spin and count method?

Only a couple of places to get the short 5th: Euro, USA 924S, Turbo, S.

 

If it's an 016 J or K (924S or 944) then the final is 3.889. So with the 'standard' 5th the total input to output is 2.838; with the 'short' 5th it will be 3.222. That's far enough apart to tell especially as one is short of 3 turns and the other is over 3 turns. Unless the LSD is worn out completely then both output should stay together making the job easy.

 

If it's a turbo (016R/S) it has a different final but the overall is the same, almost: less than 3 (2.796).

 

If it's an S (083D) then it's exactly like the 016J: 3.222

John:

 

Thanks for the information. I am going to look at a transmission this weekend and I wanted to verify if it still had the short 5th gear in it.

The short 5th gear pair is also available in the 944S and 89 2.7 944 trannies. But not the 944S2.
