Davy, heck it ain't gone nowhere. That $2500 Bowtie 700R4 is still sitting on it's pallet in my shop. I turn 67 years old tomorrow and it seems the older I get, the dang busier I get. For the past year I've been helping my wife relocate her business to a bigger facility and as a result, there has been no time for my truck projects. I am hopeful to get the tranny swapped sometime in this lifetime. If not, I can guarantee you it will get done in my next life. I plan to come back as a USAF Motor Pool Master Mechanic. Might even have an Enola Gay tatoo on my chest.
Have you accumulated all your parts? Will your 700R4 have the correct output shaft to properly mate with the NP208? Do you have the taller adapter? Have you thought about using a Derale pan with additional cooling and temperature gauge bung? Do you have the correct 700R4 dipstick? OEM shift indicator? Aux transmission cooler to mount out in front of the radiator? Are you going to rebuild the NP208 while you have it out of the truck? If so, have you thought about replacing the 208 chain with a new 242 chain? How about speedometer gears? Have you calculated which drive and driven gear set you will need to go along with your planned tire size so the speedo is correct? Have you found a NOS OEM GM flex plate? I understand these new Chinese plates are, in reality, manufactured in Taiwan, then smuggled into North Korea, then traded to the Chinese for cigarettes and beer. Oh, and I hear that Kim Jung Dong or whatever his name is found a Staples Easy Button in a dumpster and then applied a piece of masking tape across it, onto which he took a Majic Marker and wrote "NUCLEAR".
No, I am not drinking. Just having fun with you guys. Let me know if I can help with any part numbers or anything.
