4L80E into a 1990

[Patch]

Hi all....picked up two Suburbans recently....a 91 2500 4x4 with a hurt engine...but a good 4L80E and 241. My question is.....That tranny/transfer case combo....what all is involved with swapping that into the 91 1500? I've pulled and installed tranny's, engine and what not...I just do not know what specifics are involved regaurding the 4L80E.....The 90's 700R4 is blown and needs to go.....I am also putting a Corp 14 FF into the 90 and a D44 large spicer hubbed 8 lug front in the 90 as well......anyone put a 4L80E into a 90 and older? Advice would be great...as well as tips....dont do's...and etc....Thanks.....Pat
