I have a five speed manual transmission in an 87 Mera that I have owned for about 10 years. I always assumed that it was a Getrag 282 and even remember ordering a double insulated Getrag transmission cable for this vehicle from Rodney Dickman. Due to a recent issue, the transmission has been removed for the first time since I owned the vehicle. The shift fork was bent and apparently kept the engine engaged to the transmission even though all of the hydraulics seemed to function correctly.
When the shift fork was removed this is what it looked like.
A new fork suitable for the 282 transmission was ordered and when it arrived it looked like this.
The two forks were different with respect to shaft size and "ears" on the fork.
After doing some additional research, the only fork with "ears" that I can find was associated with a four cylinder (Duke) engine. I know that all three standard transmissions available (Muncie, Getrag, and Isuzu) will all directly bolt up to the V6 engine but do not really know how the internals were arranged. Based on the photos below can anyone positively identify the transmission and confirm which specific transmission this i? I will clean the transmission in a day or two and see if I can get numbers from the case but I would really like to confirm which transmission is installed to facilitate acquiring the necessary parts for a repair.
Help resolving this issue would be gratefully appreciated.

I know that the 282 cable worked on the transmission but do wonder about the apparent discrepancy wrt the shift fork. I am glad that other people also believe that it is a Getrag 282.
The Getrag in your pics is indeed the earlier (86-87) variation. The later one had the dipstick in the side of the differential housing. (The most obvious external indicator.)
FWIW, I had to replace the bushing where the shaft goes through, on another (long deceased) Getrag that I had. When I ordered the "bushing installer" tool from Rodney, the 88 tool was different, as well.

As a quick update three suppliers have failed to deliver the new transmission fork and did not even tell me that they could not supply it until after the part was supposed to be delivered. That cost about a 10 day delay in repairs. Hopefully the one I just ordered from eBay will fit and the transmission can go back together sometime next week. If this does not work out I may be forced to pay the high Fiero Store price for a replacement.
If anyone else has the appropriate fork on hand please let me know.

My 87 has a dipstick on the driver side of the diff housing. So if that's the only difference between an 88 Getrag, then there must be no difference.
A note for anyone looking for a Getrag 282 shift fork, they are near impossible to find new and extremely expensive if you do find one and are almost nonexistant. Published prices are $50 to $400 and virtually nobody actually has one. The stock answer is that it has to come from a manufacturer and is on backorder with no anticipated delivery date. I did find some used ones for $100 to $175 but one of the lower priced forks was in Canada. If you need to locate one and have no luck doing so, send mea PM and I may be able to help out.

Is it possible that you may have a very late 87 Getrag? The "common knowledge" (right or wrong) seems to indicate that the 88 (and later) Getrag had the dip stick in the driver's side of the diff housing. The Getrag that was in my recently sold Automoda had a screw-in cap in the side of the gear housing that faced the trunk, so it was obviously an earlier piece. (Every 88 I've ever seen had the diff mounted dip stick.) It would make sense that the "dipstick" change was made at the same time as the clutch fork change, but that doesn't necessarily make it true, I suppose. For the different release fork, Fiero Store makes the distinction between 88 and earlier. Likewise with Rodney and the bushing tool.
so how's your TOB and input seal/sleve to the tranny?
if the fork is bent, there is a good chance one of the other two are also a problem
They are also being replaced (if the Fiero Store ever delivers them). I am not certain right now but I will do an inspection tomorrow to see if the case has cracked also. I did not see any evidence of this earlier but the exterior of the transmission is now clean and ready for a look see.
