I HAVE JUST INQUIRED ABOUT A 4L80E TRANS. FROM FLT LEVEL4. I HAVE A DUMB QUESTION. CAN THE FIRST TWO GEARS BE CHANGED OUT TO MATCH THE GEARS IN A 4L60E? THE 4L80E HAS A 1ST GEAR F 2.48 TO 1 AND A SECOND GEAR OF 1.48 TO 1 WHILE THE 4L60E HAS A 1ST GEAR OF 3.059 TO 1 AND A 2ND GEAR OF 1.625 TO 1. IS THIS FEASABLE? IS THIS WHY IT TAKES SO MUCH HP TO TURN A 4L80E?

<div class='quotetop'>QUOTE(Mister P @ Dec 13 2006, 02:27 PM) [snapback]76231[/snapback]</div>If you are under 600 lb-ft of torque I would stick with the 65e, because of the better 1st & 2nd ratios; those 80e's eat a lot of hp.

this is what was in another thread down in mechanical talking about either an 80e or 65e from FLT... i dont know if that helps... but it kind of pertains to what your talking about'
as for being interchangable, i wouldnt know

Yes custom planetary systems are available for the 80E, and they are NOT cheap.

John Kilgore's planetary gear set is the 2.75 or the 3.00 first gear. 2nd gear also changes. It will be almost identical to what the 60e is.

Does it really matter with a higher stall converter and all that torque you have, hahah.
Sounds like a good solution James. Is your current one giving out or are you just planning ahead?
