90 chevy trk......stomp gas, noise then engine lite

200K (forgot to say 1990 trk) on tranny, brand new crate engine........no get up and go..once ypu punch it ( no matterm what speed u r) hear a BRRRR noise sounds as if gears slipping past gears (broken teeth) just for a second....then Service Engine light comes on.....BUT that is it.....you can kepp punching or whaatever.. no change once that first slippage................LIGHT will stay on, until key is turned off....

this only happens at punching stage.... you can slowly gas up and this will not happen.

plans are to rebuild or replace tranny, BUT is that the PROB!!!!

start by reading codes in the computer you can do this by jumpering the a and b pins on the aldl connector under the dash then turn the key on and the check engine light will flash any codes, should start with code 12 and flash each code 3 times.
has the timing been set since the engine was installed?
is this a 4 wheel drive pickup?
