[QUOTE="Gilaguy23, post: 434065, member: 19498"] Im no expert on ID'ing trannies but 87 thru 89 used the dreaded BA10 in the 6cyl. That being said I cannot imagine they used the improved AX15 behind a 4 banger. The BA10/5 as found in Jeeps is 16-7/8" long. Its case is split longitudinally down the center. Its case and tailhousing are made of cast aluminum and its shift control is located in the rear portion of the transmission. The BA10/5 bellhousing mounting face has five mounting studs and two dowel pins for alignment. In terms of identification numbers, it may have a "SIMI" and "3.283..." cast into the front and side of the case. Part numbers for the BA10/5 may include: 53002035, 53002838, 53003234, 53005248, 53005251, 53005252, 53005451, 53005453, 53005454. [/QUOTE]
