Hi Brian,
The worn shifter guide is not the only reason the have a 2nd gear popping out under acceleration or deceleration.
Especially, if you have a new plate .
May I advice you to open a new thread on your specific issue.
There are several previous discussions about that issue in the forum when it comes for the T-84 itself.
Perhaps that thread would give you a clue : viewtopic.php?t=291144

Re: Shifter guide plate, an often ignored small part
Interesting information collected in the French forum vehiculesmilitaires.com, where I have also shared that post in French:
Hot or cold
A metalworker with a lot of experience advised me to rather use domed rivets inserted from outside and stamping the rivet hot to take profit of the cooling shrinkage.
This gives a much better aspect from the outside and an improved shear strength, which is one of the goals.
What is also interesting is that this particular process was used in an M201 gearbox cover likely during an overhaul by the Army, as shown by the next photos published by an M201 owner(I can read Clermont-Ferrand on the gear box cover data plate)
Perfect rivet aspect Stamped from the inside then ground flush to the plate surface.
I do not wand to restart a discussion about hot or cold riveting.
This has been covered in many, many other topics .
For example here : viewtopic.php?f=4&t=79308&start=15
To me and only personally, as an engineer (ouch in electronics ), I find that interesting, considering that cold stamping was made mostly for economical reasons in the industry.
It's extremely expensive and time consuming to stamp hot rivets.
As an individual restoring a gear box cover, I'm not sensitive to that economical aspect.
I'm just interested in the best result on the long term.
And for a short rivets like that, the risk to generate the "diabolo effect" after shrinking, with the associated weakness, is pretty close to zero.
And the risk to have a moving guide plate after a while is also nearly zero.
The risk to generate this effect is also very reduced due to the short length.
Just wanted to share that information.
