I am not familiar with that page. Is the ISS hooked up to the PCM?

Turbostude

Which one? An 80 has two, correct? I unplugged the front one which I wired in for the 80/segment swap.

Front is ISS, rear is VSS. So did you reverse the wiring you changed in the trans plug if you are trying to run the relay method?

Turbostude

Yes, I reversed the wiring from the 80/segment then changed back to the 60/relay wiring. Then reloaded my 60 tune. I haven't driven it yet as the weather is bad, but I will as soon as possible.

got to drive it today, still doing the same thing. I didnt try to shift it down into first at all, just drove it to my shop. seems like it stays in second for a long time, and when it does shift out, the convertor doesnt lock....

I know with relay method, the p0785 must be disabled, i think same story for the p1860. Ill have to look and make sure on that one. The p0740 i am unsure of though.

Turbostude

I went in and deleted those DTC's, it will shift 1-2, but the 2-3 is sluggish and never goes into overdrive. Once in 3rd, it acts like the convertor is locking/unlocking, kinda like its slipping, or like its low on fluid. (Fluid is good) Are there other settings I need to change? I haven't done anything as far as the tune is concerned.
