trans hard to shift from high to low range

[WORNOUT]

Do you mean it's having a hard time between shifting between neutrals? I don't consider it a low/high range transmission. This should be your pattern on the 88.

I should clarify, nomenclature and engineering being what it is, I understand the "high" and "low" concepts...

Is the shifter moving between the neutrals? It's just not catching the upper/lower pattern?

this is my shift pattern . i ment to say the shift lever does not allow me to shift to the gear shown in lower part of shift patternr. the others are ok.

I have a Super 88 that is the same way. At times it is almost impossible to get if to come out of the high side back to low. I talked to John S. about it one time and he told me that there is something in the shift linkage that wears and hangs up, but I have not torn into mine to see what it is. I only use mine for pulling and it stays in the low side most of the time.

my experience is that there will be some rust in the spring loaded balls on the shift rail.

I agree, it could be rust on the balls or a worn poppet block. Here's an old quote from Larry Harsin:

It is the detents in the rails. The ball is wedging in the poppet block. There are 2 ways to fix it. One, get a new poppet block from your AGCO Dealer. The other way is to go in there and take the shift rail out. Then, take a side grinder and relieve the slope where the shift rail pushes the ball up into the poppet block. You don't have to take off very much.

I hope this helps.

I couldn’t shift between the ranges on my 66, I took the springs and detent balls out of the block. Cleaned the rust out and lubed the rails. That made it shift easier.

The problem is in the center shift rail. The detent ball pocket has worn. You may need to replace the worn ball and pocket with a larger ball and replace find a used one out o scrap tractor

Does your shifter move from side to side in the lower H?
