Question 1984 190D 5-speed tranny popping out of 3rd gear on rare occasions.

Just fixed the jammed shifter and now the car shift smoothly. Next issue is 3rd gear pops out sometime. It happens on occasions and I just push it back in and it is fine. Questions:

1) What is wrong? Is it an adjustment issues on the connecting rod or something inside the tranny?
2) What does it take to fix it? I can live with it if it is too hard to fix - never taken a tranny apart and do not want to get there.
3) Would changing the ATF help?

Thanks

first place id look is to see if the lever on the transmission is fully engaged when the shifter mechanism is in third.

Could be adjustment, likely worn linkage bushings again, or a loose bolt on the tranny itself allowing the external lever to partially rotate instead of fully moving the shift fork inside. On a lot of them, they have a wavy seating surface on the inbore side of the lever that matches a corresponding surface on the internal shift fork.

Whats the casting # on the tranny? It would make a difference on lever design.

Not sure about your tranny but mine have 'alignment holes" down in the shifter arms where they hang underneath the shifter. Up in the driveshaft "alley'. The rods are adjusted with a pin (nail/what ever) through those "alignment holes' Not likely the adjustment on a rods changed tho, might be worth a check anyway.
