Shifting into 1st gear

[add-liteness]

I have a Ford T9 gearbox that I rebuilt. The gearbox works well except I am not able to select 1st gear while going faster than about 15 mph.  The gearbox doesn't grind like a synchro issue, it just refuses to engage. Double clutching and rev matching doesn't help. I was wondering if anyone else has had this issue. Any information I can gather before I take it apart again will be appreciated.

Try sliding this plate back and forth.  @MV8 trick.

Maybe refresh the selector saddle if it's worn.

I occasionally get stuck in 2nd and need to open the transmission and break loose the center selector rod.  This is annoying, but easy to fix.  Then its good for a few weeks.  Could this be the same issue?  61 S2 7, not sure which ford transmission I have STANCART 1 st gear has syncro

Stancart?  Could that be "Stanpart", which would be Triumph which an early S2 most likely would be.

It sounds like oil slosh off the gears at that rpm is enough to misalign a gate. I'd check the top and side cover fit and adjustment, take the top cover off and lightly push components from side to side to attempt to see how it could block first. "Rebuilt" covers a lot of ground from everything to an "aerosol overhaul".

I believe Lotus fitted Triumph shifter extensions to Ford boxes. Take apart that turret and clean it up, new grease, etc.

Did Lotus ever put a T9 gearbox in a 7?

No, the T9 didn't come out until after 1973 when production was taken over by Caterham.

I had a similar problem. It was the shift dog. Rather that it being "round" with flats on the sides, it was worn square. I guess after 90,000 miles it just was worn down. Bought a used Spit shift dog and had to grind the sides of "ball" to make it with flats. BTW, that's what Lotus did. Another thing I did at that time was to replace the reverse stop inside near the end of the shift lever. That was a small problem finding one because the "older" ones were screwed in while the newer ones are riveted.

Thanks for your reply. Can you tell me which of the parts  in the attached  diagrams of the gearbox you had to replace and modify?

Thanks

Add-liteness. The images are for the single rail Ford trans. For the remote shifter repair, I didn't do anything to the trans internals. I replaced the shift dog which is at the end of the shift rod on the Triumph housing. The shift dog goes into the shift rails. See Moss Motors - Spitfire- External Gearbox, 1962-74 (3 rail) . Its part #77, unfortunately NA. Try the  Triumph crowd, they should have one as that was where I got mine. At the amazing cost of $25 plus shipping. Hope this helps. BTW, I have a complete aluminum remote shifter which is a definite upgrade if you are interested.

@joe7 Can you please post a pic of the remote shifter you have?
