Mitsubishi J26 Jeep KM141 gearbox question
It is getting difficult to change down into 2nd when the box has warmed up. So I am thinking of changing the 4 speed Km141 box or getting it re engineered.
I would appreciate any tips or suggestions people might have.
the engine is the original 2.4 4 cylinder 4G53 ASTRON.

This problem is usually attributed to a worn out Synchroniser Cone/Ring, also this problem can be compounded by worn out Gear Box Bearings.
Looks like your JEEP A Gearhead in Need » GEARBOX MAGAZINE
As the the oil warms up and thins out, the clearance between the Synchro and Main Gear Shaft increases, worst case the Synchro may jump out (just a little bit)and the gearbox will get stuck in that gear.
You can try using a GL5 85W140 Gear Oil, and see if there is any improvement.
After that you can decide on rebuilding the gearbox or changing it.
PS - Please post some pics of your JEEP.
