What 5 speeds interchnge in the 4WD pu for these years. Working on a 1988 (titled as but the door tag says Aug 86) with 22r? The trans code on firewall says G52 but the emissions label under the hood also says 3vZE so I'm not sure of components. The trans has an 8 bolt front bearing retainer, is aluminum, and 4 bolts hold down shifter plate
