Mounted everything back... very hard to shift and would only shift into 2nd and 4th. Can't get it to shift into R, 1, 3, 5
I need to get on a plane in a couple of hours.... thinking of draining the transmission to see if there is some horrible scene in the oil...
Any thoughts?

Jamie,
Did you change the length of the forward static rod?
With the car level, the shift lever should be plumb. If it's not, use the threaded front ball cup to shorten or lengthen the rod.

No changes to the lenght. I left it as it was. Something in the tranny is not letting it shift to those gears (all gears in the forward most position). Very, very hard to shift to 2nd and 4th. Clutch engages and disengages without a problem...

Jaime,
Sounds like the shift rod to the transmission can move fore and aft only enough to select the "rear" gears (2 & 4) , but can not move forward past the neutral position to select the ones in the upper gates.
IIRC, the shifter rod looked kind of rusty where it goes into your transmission. Can the rod move through all its posiitons when disconnected from the shifter mechanism? Worth checking.
Also, wondering if you put the stick in neutral, lubed up the rod and from below, "helped" the rod move with your favorite tool ... I wonder whether it might free up. If not, it's probably a detent that's jamming (had that a few years ago on a Jag transmission), and that sounds like it's time to delve into the G50.
Good luck,
.. Gregg

The rust is really some cosmoline... I cleaned that. Spraying some WD40 and then some of the other stuff (can't remember the name) it got a little bit loose. This was with the linkage removed. But never got past the neutral position. Even with the car on the lift, me inside trying to shift it and my father-in-law under the car trying to help it a little with some craw bar persuasion... We did not wanted to make it worse so the persuasion was minimal...
Can that area be worked on in situ or tranny must come out?

Jaime, I don't recall whether you mentioned how the shifting problem came to be ... did it gradually get worse, or was it sudden ?
Fire up PET, and have a look at illustration 304-05, which shows you all the detent mechanisms in the G50 box. I suspect either that one of them is sticking (wont retract), or that one of the mating detent recesses has worn and is jamming its mating plunger (classic vintage Jag Moss box problem).
If the car was in storage in a damp location for a while, the problem could be a bit of rust causing the detent(s) to stick.
If it gradually got worse (as evidenced by the deteriorated shifter bushes), it could be worn detent recesses. Either way, I think you'll have to drop the box to dismantle it.
Good luck,

This is a bummer... car will have to be parked until I can raise the funds for tranny drop and work.

Nope... car parked until I can raise the funds for a tranny rebuild... and still trying to decide if I take out the engine and tranny myself of leave it all to the shop.
The car will need to sit until September when I can afford the fix.
I did take it out yesterday for a drive (pushed it out the driveway since I can't engage reverse, then drove around in 2nd and 4th)...

Jamie - hopefully you'll get the cab back on the road soon. I am re-entering the P-car fold having just picked up a '90 C2 Targa this weekend. I missed my C4 (sold for the money to use on a house downpayment) horribly - so when this C2 popped up for a screaming price I grabbed it.
On the test drive the shifter failed on part #15 in the drawing and we were left gearless (vs stuck in 2nd). But a few zip ties allowed me to get back out on the test drive after we saw what the problem was on the lift.
So good luck! And...
I'm baaaaaacccck!

I just did the linkage bushing change on my 91 C2 over the weekend using p.n. 928-116-145-03-M100 from Pelican. Very easy to do and the shifter feels much tighter now. I had the same problem where the bushing was eaten away and the rod dropped to the pan leaving the car stuck in second gear. Using the bushing from Pelican is much cheaper than having to buy the entire rod.

Does anyone know if the same bushing 928xxxxxxxx can also be used to replace the bushing in part #16? While I'm at it I may as well renew both...
