Can a defective o2 sensor have an effect on shifting pattern of an automatic transmission-4L60E?

Question

This is a '97 C1500 Silverado and the problem started when the tranny was rebuilt professonally at 115k-the tps was replaced at that time with no success. As long as it is in 3rd and not OD it won't do it. At 215k it went out again and was again rebuilt. Still not resolved. Now at 235k it is starting to shift hard going into 2nd and very slightly going into 3rd. The codes are showing "insufficient catalization" per a dealers review. If it is in OD and it bangs, all I have to do is pull over, shut it off for a few seconds and start it back up. It's great for another 30 min. or so. If i just put it in 3 it won't do it again.

Answer 1

If the defective O2 is an anyway causing the engine to misfire it can make the transmission feel very "confused" for lack of a better description.  On the other hand, if your transmission is slipping when it goes to shift, then it's not an O2.

Answer 2

well it sounds like u either have a blazer, S10, Astro, or camaro these were common GM vehicles that had the 4l60-e tranny and no it should not BUT one sensor that may cause it is a faulty TPS (throttle position sensor) that is located on the intake manifold... good luck!

PS>these are VERY sensitive transmissions...
