I have an 81 gmc 1/2 ton w/ 305 motor.
I have a 700R4 transmission from a mid-eighties suburban.
I want to put the 700R4 in my 81 gmc, but the wires don't match up. Currently I have 2 wires to my tranny but the 700R4 has more wires. how should I proceed?

You'll likely need the TCU and the associated harness from the 700R4

I have just purchased a 91 1/2 ton 2wd u/p that the transmission doesn't work. A friend has a 700r4 with 25000 mile on it that he swaped out of a 89 camaro with a 350 engine. my question will this camaro tranny fit my 91 u/p with no problems?

heres my story:
bought an '85 k10 scottsdale a year ago. seller said the tranny was freshly rebuilt.
I took the next year rebuilding the engine, ignition, carb., intake, etc.
Finally got her running and drove her to the exhaust shop to have the new pipes welded up. When I drove her away from the shop, the speedo didn't work. No big deal, I thought... probably just the sensor got disconnected while the welder was under the belly or at worst, faulty.
a dozen miles later, the tranny "slips" to 1st gear when should be shifting from 2nd to 3rd and in 1st it stays. If I run it in 2nd... no problems.
I checked the fluid for the first time since buying (about 100 miles tops)... bone dry. I have added fluid... but no difference.
So before I buy a new tranny... any thoughts, ideas, or suggestions?
Thanks for your expertise.

I recently bought a 68 camaro with a ZZ502 and a 700R4 transmission. The previous owner got the trans from a 98 camaro. The tail housing is the 3 bolt type, 2 on the bottom and 1 on the top. The problem is that I'm having trans fluid leaking from the rear most bolt hole on the bottom. I'v checked all around the area to confirm that. Is there a seal or any thing thats leaking or possibly a crack and I need to replace the tail housing? Any answers to this will be greately appreciated.

You may want to reference conversion kits on the 700R4...I'm sure you can find something on the net.
