Iraq eh? Looks like we're trading locations. I'm outbound in a few months.
Here's the list of stuff you'll need:
- PCM reprogrammed (special order) with the 4t65 transmission data. If you don't, you won't have the correct information it needs like gear ratios, MPH information, etc, and your shifting/MPH reading will be all out of whack.
- 4t65 transmission (duh) WITH the driver's side primary mount. You'll need the base mounting plate that sits on the frame of the donor car (van) also. I used the one from a 2000+ Monte Carlo w/3800
- Dog-bone mounts from radiator head panel to engine (this is your torque bracing). I use the ones from the minivan (chevy venture, etc.) because the engine bay is smaller and the right length. The dogbone assemblies from GM cars are not useable because those have longer engine bays than the N-body.
- Axles custom made with 4t65 inners and 4t45 outers, or use shortened 4t65 outers if you want to change to gran-prix hubs. The outer splines will not match up.
- flex plate from whatever engine your torque converter/trans came from. 3800 and 3400 center bolt patterns are the same on the flex plate, however the outer bolt pattern on the torque converters are not.
- custom made wiring harness to change the signals to the transmission.
- weld the lower base-plate mount support to your lower frame on the driver's side.
Bingo, you're in business.
