Now my F**king 727 3 speed wont shift down I have to put it in first, second, and drive if i don't want to start in top gear at the figgin stop light. Whats wrong with this retarded POS?

 

Sounds like a problem with the governor in the transmission.

Your problem is probably this--> 1989w250's Sig:1989 Power Ram W250 with .Denny T stage 2 fuel pin, Some DDP 100hp injectors 4'' straight pipe up to custom stacks, Performance air filter and intake, Glow shift three gauge dash mount pod with Boost, Trans temp, And EGT gauges, 92 grill, New shocks, I painted the valve covers and some other stuff under the hood Soon to be twin turbo and 5 speed.

That seems like more than a stock trans can handle if the pump is cranked up.

 

That trans is stonger then you think. I would say it more the age not the mods done to it. Yes mods didn't help it any. Sounds like a valve sticking in the valve body or the governor weights sticking.
