Have a 91 V6, 3.1, from a Camaro in my 47 chevy, was told it was a 700R,(4L60 a different case) have the kit for the lock up torque converter, Electrial plug is OK but where you put the new sending unit, by the servo, the plug they tell you to take out isn't there? There is a plug on the other side of the trans, a little higher up, the plug has a machineed end on it. Anyone know anything about this?? :huh:

I recently swapped my transmission with a junkyard trans (im not expecting the world here) but everything seemed to be ok until i felt it shift quite harshly. I got DTC P0730 incorrect gear ratio. According to the charts ive looked up from fellow members(http://www.gmtuners.com/transmission/2004_4T65-E.pdf) it should be the same as the one i took out.

My original trans is 4RDB and the junkyard one is 4LDB

I am certain I plugged in everything and connected all grounds. Anyone else encounter this?
