I have the 2006 cadillac dts . 4t80e trans. For about two months now my cars been down and I've been driving myself insane tryin to figure out the problem i was drivin home from work and my transmission juss stopped workin but prior to that I only had a 2-3 hard shift that's it. I replaced both shift solenoids just because I dropped the pan, and replaced the output shaft speed sensor. When both front wheels are in the air and I put the car in drive the wheels slowly spin but are not in sync with the throttle or engine. But when the car is not jacked. Up all tires on the ground no gears will engage reverse nuetral drive 3 2 1 nothin engages but it wants to but it's very weak and wont engage. I have no check engine lights I run my obd reader on it dozens of times to watch live data. Theres a whining coming from the side case, the flywheel is bolted to torque converter they both spin when I put my ear close to the side case it sounds like its comin from right there at the top but when I get underneath and look at flywheel and converter it sounds like its comin from down there also i do have some pics though I could use help with an opinion on the pics. My obd tells me I have negative engine torque.. and I believe my TAP system psi are messed up. Its somethin to do w pressue system I strongly believe. No P codes .
