Welcome to the site!
Have you followed the linkage down to the transmission and looked for any binding and also confirmed that the linkage is tight?
If it is not an adjustment than can be made, I'm afraid it may be something internal.

Assuming you got all the air bled out of the system and the linkage is not hanging up sounds like a sticky internal valve or maybe a partly plugged oil passage.
hey gang thanks for such a speedy response .. linkage is fine and i'm not sure about the air in the pump. is there a process on bleeding the pump? can i find them on the site or do you know what to do? again thank you for all your masterfull input from all.
The purge procedure might be listed in your owners manual. If not, I'm guessing being Crafstman odds are it is probably a Hydro-Gear unit. You might see a manual listed for it here:
Hydro-Gear Service Repair Manuals
Below is the procedure I cut and pasted from their g730 manual which seems typical of how all of them are bled.
"The following procedures are best performed
with the vehicle drive wheels off the ground.
Then repeated under normal operating conditions.
If this is not possible, then the procedure
should be performed in an open area free of
any objects or bystanders.
1. Disengage the brake if activated.
2. With the bypass valve open and the engine
running, slowly move the directional control
in both forward and reverse directions (5 or
6 times).
3. With the bypass valve closed and the engine
running, slowly move the directional control
in both forward and reverse directions (5 to
6 times). Check the oil level, and add oil as
required after stopping the engine.
4. It may be necessary to repeat Steps 2 and
3 until all the air is completely purged from
the system. When the transaxle operates
at normal noise levels and moves smoothly
forward and reverse at normal speeds, then
the transaxle is considered purged."
