Some background:
Recently purchased, shifted a little rough, noticed the fluid was dark, and planned on changing it a week later. AT light came on and a code for solenoid "D" stuck off, and 4/5 gear would slip. Dropped the pan, new filter, and did a drain in fill 3 times until fluids came out bright red. Put some Amsoil ATF in that meets the M-V requirements and a bottle of Lucas trans fix, shifted butter smooth and zero slipping for about a day. Then the fun stuff, drove it and started slipping in 4/5 again so drove it home and tried to reverse and nothing...
So now when I go from neutral to Reverse the car jerks forward like I put it in Drive and won't move and barely revs to 3k rpms.
-Reverse lights turn on when shifted into R
-Disconnected shifter cable to make sure it wasn't out of adjustment, its not.
-2008 Mazda 3, AT 5 speed with 135k miles.
What are the odds of all those drain and fills plus the lucas additive that some debris got dislodged and blocking a passage way to Solenoid "D"?
Any help would be appreciated.
