Long story short Im tired of the BS TBI crap in my 1993 Chevy K1500 4x4 and so i bought an 03 5.3l LM7 to swap into the truck. Im dead set on using the early non-PWM 4l60e thats in the truck now becuase i just had it rebuilt less than 15k miles ago. So I have already purchased the the machined crankshaft spacer/adapter with the six holes in it. Can I or can I not use the stick dished 5.3L flexplate with the spacer? Does the spacer go on before or after the flexplate?

About the trans... i thought i read that I could get a newer 1995+ harness and tcc solenoid and put it in my transmission to fool the computer. Anybody know?

Stock dished 5.3 flexplate will work, dont bother getting the bolt on spacer and longer bolts just get the stepped ring looking one. As for the trans not sure i think yours only uses a 12 pin connector and the 95+ use like a 14 pin, no clue what the differences are but i read it wont work. Im doing the same swap in my 1996 tahoe

Just saw you already have the spacer bought, flywheel then spacer.

Check out the automatic trans section on this site.If mrvedit and clinebarger say no,it is more than likely true...

With my brothers 94 s10 which uses a 4l60 that has a non pwm tcc we did not change anything on the round connector that goes into the trans and I can't remember if we left or cut out the two trans range connectors but I know that we didn't use them. As for the tcc brake the purple wire (pin 33 on the blue PCM connector) that needs to be fed with a constant 12v that opens up when you hit your brakes. We did this using a relay, your truck may have a switch already down by the brake light switch. The flywheel sits on the crank then the spacer.
