Default 700R throttle input Questions

Help Please

i am getting ready to swap a 2004 5.3 into a 1992 K5 Blazer. Presently in Blazer is 5.7 and 700R. When you swap onto the 700R, which flexplate/bolts should I use? And what thickness spacer if any? Also the 2004 has drive by wire. Easier to switch to cable throttle to have TV cable hookup for 700?

I have a early 460le and cable throttle so looking for easiest way out.

When I have computer programmed, if I use the 700, setup computer like a T56?

I'll give it a shot here.
I can't help you witht he spacers for the T-700 but if you are keeping T-700 you'll need to switch to a cable operated throttle body (modified for TV cable) and have your PCM reprogrammed for a manual.
Easiest way is to use the 4L60E,and keep your fly by wire (if you have the pedal and TAC module)

Thanks:

Are all 460le trans the same from the electronics end? I have heard that some early ??? are different. I have a harness from a 2004 2wd and the swap trans will be 1999 4wd. I think the transfer case ect from the 700 will fit.

Still wondering about the spacer and using the 700. If I am going to have any tranny and or transfer case issues I think it would be easier to stick with the 700.

Dont yet have the TAC stuff or ECM computer, it didnt come with this motor. Anybody got one for sale?

Don't know if this will help or not. I'm using a 700r with an ls1. I'm using flywheel pn12551367,spacer pn12563532,bolts pn12563533. I do believe the 5.3 is the same as a 5.7 so I don't see why these gm parts won't work. Good luck John

I'm confused.... if you have the matched trans with the 5.3 (4x4 4L60E if I read correctly) Why wouldn't you use that? Less PCM work, stock harness plugs in etc., etc,....

some info on that flexplate #12551367...it does NOT bolt up to a 700 converter. it is considered large bolt pattern, which is 11.5 inches diameter.the 700 converter is smaller by about 1 inch!..I didnt want to enlarge or egg the holes, so i am having a custom converter made.

Sorry. Let me try to clarify. I have

1. a 2003 5.3 without harness or ECM or TAC module or pedal

2. A 4l60 from a 1998 Silverado 4X4 (? on condition)

3. A 1992 Blazer 5.7 with 700R.

I have heard of people using a 700R behind a LS motor. To use a 700, you need a TV cable to control shift firmness ect. The only real way to do that is with mechanical throttle linkage.

Since I need to buy a harness and ECM, the early (pre 2001 cable throttle) are easier to find and cheaper. Then I know the 700r I have in truck now works well. If I use the earlier circa 1998 4L60, I am not sure that the sensors ect are the same as with the 2003 motor I need the ECU to match.

Thanks
