P068 trouble code cadillac

Have a p068, p076, and a p080 trouble code, I have already changed the pressure soloniod in tranny but still getting tranny codes. I put a different tranny in out of another 94 eldorado is there any change that my ECM is not communicating with different tranny like it should? Shifting hard and my cruise is not working but that could be that I got vacumn lines on wrong when I put it back together

SOURCE: 1995 Cadillac ETC has hard shift (all gears work)

yes change fluid. if that dosnt work buy new shift solinoids. and replace them. also check all the wiring from transmission to pcm and from conector to solinoids when u take the pan off. just disconect the solinoids. and use a digital multimeter innva brand put it on continuity and touch wire after wire till it beeps indicating wiring is touching . some will beep because thay are still conected and would have to remove transmission to disconect them. i just had this exact problem on my 94 sls . i replaced solinoid a-b and did a fluid change and checked the conections going to the transmission. and it runns good now

Reverse gear doesnt engage


I would try draining the fluid and changing the filter and fluid (with the oem spec fluid) this will give your tranny a lil more pressure to help engage the reverse , hopefully the filter is just plugged or gummy thus blocking fluid passage, its the easiest fix b4 going to the expensive tranny shop$$$ (they may also be able to adjust the pressure applied to the reverse bands, but ithey almost always seem to want to sell u a new transmission first so beware, try a few different shops to see if they can adjust the pressure, if the filter change doesnt help

Caddy stalls on me?


Scan the engine computer for trouble codes. Check your fuel pressure-low fuel pressure will cause stalling. Does it start right back up? If so, maybe a problem with the idle control valve or motor.

Cadillac escalade transmission problem TFP switch trouble code and how to fix the delay shifting my car is cadillac escalde 2008


Transmission fluid pressure switches, i would say you have internal transmission problems, weak pump or internal leakage but to have four bad pressure switches is very very unheard off, i would have a transmission shop check it and maybe do a pressure test and leak test. it sounds like it may be time for a rebuild on that transmission.
