Answer 2

2000 A6 4.2  P0730 P17114

Found the connectors to be dry and all connections to have continuity from sensor to the computer connector under the mat on the passengers side....took the sensor out and tested it ...came in at 1k ohms ...the thing is when i installed it and connected it then  tested it from the computer connector while rolling the front wheel  with  meter set on Ohms the reading shows ohms to begin with and open if u spin it by hand faster....with the meter on A/C it shows power but with breaks in between....tried doing the same test with the abs sensor and never shows an open condition....Im thinking i should get a sensor and go from there....did i miss any other test?Also inspected the front connector in front of the transmission and no signs of corrosion or water contamination...i should have stated b4 that i have reverse instantly but need to rev it when in drive and the nasty clunk comes and the gear selector on the dash turns red (guess thats the limp mode)and then after reving engine the car starts moving with alot of what i call slippage....eventually down the road the faster u go the better it feels...looks like its in 4 or 5th gear looking at the rpms....hope this is helpful...already changed the fluid and filter on the trans...previous change was done 50k b4...the fluid looked good and no metal present ...the magnets had a minimal black film....

Thanks again
