No 95 4l80e 4x4 had an output reluctor wheel stock. The hole is there and it may even have a speed sensor installed instead of a dummy plug, but if it's stock, there is no 40 tooth reluctor. ONLY 91-93 4l80e 4x4's had it installed. Many have said they had a 94+ with one until they removed the OSS, and looked inside to find nothing(or the 21 teeth of the adjacent hub). If your 95 has it, somebody put it there other than GM.
