Anyway the 6 banger will not be totally stock. I have built them before and got decent power out of them.
The 86 Monte should have a 700R4, not a 200R4
The torque converter lockup funtion on both transmissions is computer controlled, but the shifting is not. I believe you can buy a stand alone controller for the torque converter lockup if you wish. I'm not sure, but IIRC, on some of those transmissions it was detrimental to NOT have the lockup function engaged when traveling any distance on the freeway. I think it had something to do with additional lubrication that was supplied to certain parts when the lockup was engaged not being there, and starving certain parts for oil(trans fluid). I would also suspect there is a fix for that if you want to run without lockup. Talk to an expert or do some research.
