Engine Or Tranny Problem,how Can I Solve It

[Steyn Moolman]

I have a 1995 GT with AODE transmission.It shifts from first to second at 4800 rpm,second to third at 5200 rpm and third to overdrive at 5200 rpm when I keep my foot down to the floor.The engine is struggling to rev past 5000 rpm.Is shift point on the transmission wrong or does the motor need a tune up.I am not living in the U.S.so there is no one that can help me here.I will appreciate any info.
