Ok,I like the 4L80E.it bolts to the same pattern.but.I have one in a`91 Suburban 3/4t diesel 4wd mated to a NP241.That`s the only year for a RH drop transfer case and 4L80E.But,they mate the same as the late NP205 and NP208.the GM diesels had manual injection through`93.I`m not sure what year the 4L80e started.the diesels would have a stand alone computer/controller for the trans.
