Thought i should start a new tread as i'm sure i will have a few question that others might find helpful. After this swap is complete and running properly i will begin the 427 swap.
1989 v-2500 suburban 5.7tbi/TH400 4.11 gears with 1228747
Swapping in a 1227747(asdz) from a 1989 G20 5.7tbi/700r4 2.73 gears.
Plugged in with no wire changes:
Started: OK
Idle Park: good
Idle in gear: OK(could be aftermarket cam)
acceleration: slight stumble on take off
transmission: shifted OK
CEL: NONE
Problem noted:
Transmission kicks down in to low gear at speeds over 30mph. TCC being engaged do to ECU set-up for 700r4
slight stumble win taking off from a stop on low speed.
