Sorry for the delay,I was on security detail for the grand/children a very satisfying job!
,It called babysiting,in some circle's,, But with this crew It requires a firm reasuraning voice,demenor, and some degree of child physcology,,,
On the 4L80 E,It is just what Bill said ;
It is a heavy duty trans,,, a 400 THM with overdrive usualy found in 1 ton trucks or 3/4 tons and maybe 1/2 ton, special order heavy duty towing. Depend's on what years but could be ordered in a lot of application's ,field service body trucks,,, motor homes,,.Snap on Truck breadbox Usualy behind diesels and the newer motors,Note my Son in Law told me the diferance in rebuilding the
700 R 4,,,,4L 60 E,,,, 4L80 E is "more money" involved than a 700 R 4 because of some diferrance in rebuild kits , replacing the convertor and the extra shift solenoid's,worn "valve body's"with up date kits to make it work more efficently with the
load's and heat imposed on the unit's.,,,,,,The newer models need to be upgraded on rebuild's ,ocasionaly in some,, not all,
EDIT 8-8 07
The 4L80-E
But all in all the size of the trans is NOT
close, The exterior is reinforced with webing,
The bell housing is "larger" some floor modifictions needed in the bell housing area also,, the The trans is longer, and the pan is deeper and longer,, Much like the HD manual trans .It is
OVERKILL,,,,Hope this answered your question"s.
Later I will give you some billing we did on a couple of tickets with parts replaced,, every rebuild is a little diferent, But I think you will get the picture. Mike
