Lack of rear lube style output shaft for pre 1987 AODs’. Failure with 3.55,3.73.

[Gasman]

Hi, new guy here. Great web site. Here goes nothing. I have a 1987 AOD, Conv. GT (heay car) with 35k original miles. I’m Installing a Baumann AOD Valve Body Recalibration Kit , Overdrive “A” Servo Assembly, and going to use Red Line AFT transmission fluid. Have already installed B&M Transmission cooler. My understanding from what I’ve read is that 1987 AOD’s do not have the rear lube type output shaft (1988 was first year). Because of this going to 3.55,3.73 or 4.11 rear end gears I could have transmission planetary gears failure do to lack of lubricant. So my first Question would be is this true? If it is true will my Transmission Modifications take care of it? Second question would be is they’re anyone out there with a 1987 or pre 1987 AOD with 3.55,3.73 or 4.11 gears that’s experienced problems or no problems? My Goal is to have 275-290 rear wheel horse power with this OEM transmission without killing it. There will be non-of that 1,d, 1 stuff going on. Thanks in advance.
