Because you are dealing with a late, late model 4L60E, you will need a custom converter, different flexplate, or have someone install an earlier input shaft in the trans, I think....... If you were dealing with an earlier model 4L60E, you would of had no problems. I am going to dig through some stock converter books and see if I can come up with one that will fit your bill, I am thinking of one in particular but I have to check the specifics of it.
I will keep ya posted!

Been there, done that. Most cost effective (cheapest) way for you to get out of this is get another transmission or a swap converter. I am still digging to see if there is an oem converter that will work.

Just curious -- what would be the difference (distance) between my longer crank flange + flexplate compared to the regular 6.0 crank + factory spacer + flexplate.


*** also found 2 - 4l80e
1 - 00' OBCP w/original converter
1 - 06' MPJ w/original converter

will both these
what is wiring plug difference
what is converter difference

ooooh ooooooh now I like were this is going... railroading someone in to a 4l80e YES.

The first one is a 4x2 trans out of a 3500 truck, this is basically what I'm using. The wiring on these SHOULD both be the same (I had my harness made for a 4l80e without telling him what year), but will require an extra VSS (has a different name but its a vss type sensor) than the 4l60e wiring.

The 4l80e is a nice place to go, stock it holds these motors no problem.

Any more suggestions?

just sell the 4l60e you have and grab one of those 4l80e. Even in stock form it should hold without much of an issue.
I see it this way'
4l60e (free) + trans upgrades shift kit, servo etc (250-400$), + custom converter ($900) = $12-1400
OR
Driving condition 4l80e (~$500) + extra vss plug ($15) = $515 Leaving you with 5-700 in cash left over, which you can use to get an upgraded stall converter if you want, or use a stock verter and save the extra cash.

You can swap the Input drum & Stator support shaft for "298mm" versions & run a 98 & up 4.3L converter, Redrill the flexplate......Problem solved.

Thanks guys for all the help and education.

I got a 5.3 laying in the floor -- I'm just gonna use it in front of the 4l60

I'll get a 4l80 to go with the 6.0 for a later build
