Ok I'm having probs with Trans not shifting in reg drive

From a start it won't even spin the tires but put it in low 1 and it will

While in drive it's like starting in 2nd

Trans is rebuilt --new selenoids etc

Ok the ?s

I checked the Trans codes and cannot get it to flash 10x
Not even Once

What are the tcm numbers --I have 33p11 & 45p00
Last one is The only one that really works it seems

Tps is new and set at .45

Engine runs fine

But first I believe I should find out why it doesn't flash

1990 auto 2+2 na
Engine built n dynoed 259/244 yea I know not tt
Trans built n from z1

If the trans is rebuilt and full of good fluid, then it's probably the trans controller itself that's shot

Have you tried contacting Z1, they are the ones that built it. Did it just start doing this or has it been doing it since you git back from Z1?
