Ok, I tried to install a new tranny mount in my '83, as it has only a rubber washer between the tranny and crossmember. I bought a tranny mount that is supposed to fit the car, an 83 GS 5 speed. However, the mount would not fit, as the bottom of the transmission has a closer bolt pattern than the mount has. I know the trans has been swapped, due to the shifter being about 1-1.5 inches farther back than it should be. The shifter tower hits the back of the hole in the floor, even though it has been lenghtened a little, via the BFH method.
I have determined that I will likely have to make something fit, which is not a problem. The problem is, I don't know what the tranny is.
Here is a brief description, based on what I could see.
The shifter sits about 1-1.5 inches farther rearward than stock.
The overall length seems to be the same as stock.
The case is not smooth, it has a ribbed case.
It appears to fit the 12a perfectly at the bellhousing.
Any idea as to what tranny I have in this car?
I have a feeling it is a later model, but I have no clue as to what it originally fit.
4K in 5th = 75-80MPH w/ 205/50-15, is this close to the stock ratio? Of course, this is assuming the tach and speedo are somewhat close to accurate.

 

Just from the description of the shifter placement and smooth case, it sounds like a 2nd gen NA tranny.

 

Nope !!!he said the tranny has ribs on it So YOU HAVE A TII Tranny ...........LUCKEE!

 

Not a smooth case, has ribs around it.

 

IS it the forum or mY computer is slooooow?
YOU HAVE A TII Tranny

 

Sorry, misread that. It is more than likely a TII. I think most of the older ribcase trannys were 4-speeds.

It's the forum that's slow.

 

Forum seems to be a little slow.
TII Tranny huh? cool. Thanks
Guess I got my $500 worth when I bought the car. Now to just aquire the 87 13BT the was offered to me a few days back..........................

 

$500





I hate you!

 

Thanks

 

Anyone have a pic (or a link to a pic) of a T2 tranny? I would like to have a visual, for comparison. If this is indeed a T2 tranny, I would likely need to do further investigating, in the event that I ever need to replace the clutch or starter.
From what I have seen, these appear to be different between a stock 1st gen, and the T2.
I tried looking in the archive, but all threads relating to a T2 tranny swap seem to have lost the images that were once attached. This is where I seen the info about the clutch/flywheel/starter differences.
Thanks.

 

Bump.
Anyone got pics, so I can tell which tranny this is?
Also, would it be possible for me to drill a couple new holes on the mounting location, so I can use the stock 1st gen mount? That is what I am currently contemplating.
While I may have gotten a killer deal when I purchased this car, it has a downside. I purchased it at an impound auction, which makes contacting any former owners quite difficult. Also makes me have to become a "detective" of sorts, to determine what has previously been done to the car.

 

The older 5 speeds looked alot like the TII tranny they both have ribbed cases and I know the early ones had a bolt on aluminum pan on them and I pretty sure the TII had the same ribbed cast aluminum pan as the early units. I had a 1974 RX3 with a 1976 RX3SP 5 speed in it that I got the tranny as a basket case.
