Case 580C 3rd and 4th gear

[outlawspeeder]

I rebuilt the Shuttle Transmission and was expecting better out of 3rd and 4th gear. In 1st or 2nd it will climb a steep hill with a load but in 3rd or 4th it will it will barely get rolling...

Is that normal for 3rd and 4th?

I have to drive this about 7 miles (road mostly) and really don't want to run in 2nd all the way there.

The rebuild didn't include the torque converter but I would expect that to effect 1st and 2nd too?? Also just did a fluid change on it.

Any thoughts of what to look at?

Does the motor labor or lose rpms when it is in 3rd or 4th with accelerator to the floor ?
Do you have any idea what the wot rpms are with the transmission in neutral ?

I'd say from my experience that's normal until they came out with lock up converters.

Ya the C that I use to have was same way.Get up some speed shift to 3rd and fourth and would travel on level alright and a little grade but not much.

TY I was starting to think I screwed up on the rebuilt. I did have to replace the forward piston. It had broken had no power going forward.

torque converter stall test is what you want to do. But yes, it seems normal to not go up any grade in 4th.

That condition is certainly normal.
But without knowing how severe it is, I think a proper diagnosis of the wot engine speed and the torque convertor should be done to rule out any problem with them.
