00 GT , no 4th gear

[Scudman64]

ok, so i just got a great deal (i suspect) on a 00 Grand Prix GT, its completely stock, lots of miles, but its in better shape than my 02 gtp, anywho.
it shifts just fine, but it doesnt go into 4th... ive only owned this car for about an hour now. so i dont know too much about it yet, i drove it home, and here i am. lol.
any suggestions?

probably the splines on the 4 gear clutch shaft are striped out

really? i thought it was 01 the hardened 4th hubs were released
i know GM knew about the 4th clutch hubs stripping as early as 99

so when they changed the manifold pressure switch logic/internal range switch in 03/04 they hardened the 4th clutch hub?....damn that took em a while

If you would quit hunting deer with the 2002 the 2000 probably wouldnt be in better shape... also if you give the 2000 to me i will put my trans in it.. problem solved...
