Hard late shift=governor.

So read the TSRM on our electronic controlled transmission.

Tranny Cable at throttle?? Is it adjusted properly??

That would be a real good start.

Check for codes! I would also check the fluid. If it hasn't been changed in awhile dirty fluid could cause problems such as this.

I might be off but I had a ford van that would do the same damn thing, and a tune up goes along way. Especially if you don't know the last time it was done.
