Fluid Level to high

Overheating of transmission

Various other internal problems

cloged filter inside transmission will couse that bad tork converter or cloged transmission cooler inside your radiator need help on how to diagnose problem let me know ill gide you

Both codes (obviously) point to transmission related problems. The DTC P0700 means Transaxle Control System Fault Conditions and the DTC P0742 code means Torque Converter Clutch (TCC) - Stuck On.

The DTC P0700 code is for information only and the next step is to check for transaxle codes in the Transaxle Control Module (TCM). So you'll have to have the dealer or another qualified shop/technician pull the transaxle codes from the TCM and go from there.

On DTC P0742, Torque Converter Clutch Solenoid Valve (TCC Sol. Valve) is a normally-open exhaust valve that is used with the Torque Converter Clutch Pulse Width Modulation Solenoid Valve (TCC PWM Sol. Valve) in order to control fluid acting on the converter clutch apply valve. The TCC Sol. Valve attaches to the transmission case assembly extending into the pump cover. When grounded (energized) by the Vehicle Control Module (VCM), the TCC Sol. Valve stops converter signal oil from exhausting. This causes converter signal oil pressure to increase and move the converter clutch apply valve against spring force and into the apply position. In this position, release fluid is open to an exhaust port and converter feed fluid fills the apply fluid circuit. The converter feed fluid applies the TCC. When the VCM no longer provides a ground path, the TCC Sol. Valve de-energizes and apply fluid exhausts, releasing the TCC.

Condition: Some customers may comment that the transmission shifts hard, a shudder/chuggle is felt on deceleration or the Service Engine Soon (SES) light is illuminated.

A technician may find DTC P0742 set. Customers with 4T80E transaxles may also comment on a "bump" feeling at approximately 61-68 km/h (38-42 mph) when they lift and then tip into the throttle. There may also be a concern of whine noise in 3rd or 4th gear with or without the Service Engine Soon light/message displayed and with DTC P0742 set.

Correction:
Note: DO NOT REPLACE THE VALVE BODY AND PUMP ASSEMBLY.

Important: This test is not applicable to the 4T80E transmission. Instead, replace the TCC PWM solenoid on vehicles with a 4T80E transmission using published procedures for the vehicle being serviced.

Perform one of the following diagnostics:
• Test drive the vehicle with the Tech 2® installed, Monitor TCC Release Pressure. The Status will be YES until TCC applies and then the display will read NO. If during acceleration the status remains NO and the upshifts are harsh and during deceleration the vehicle shudders during downshifts, suspect the TCC PWM solenoid.
• With the Tech 2 installed in the vehicle, start the engine. Build the vehicle on the Tech 2®. Apply and firmly hold the service brake. Place the transaxle in D4 and command Drive 3 with the Tech 2®. If the engine stumbles and/or stalls, suspect the TCC PWM solenoid.

Replace the TCC PWM solenoid using published procedures for the vehicle being serviced.

Hope this helps; and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment.

Have a nice day and thanks for using FixYa.

check your trany fluid .auroras transmission low fluid or currupted fluid couse overheat even witrh fans working

only 4t60e transmissions work if its a 4.9l . only 4t80e work with the cadillac northstar 4.6l

the aan and mln is the modle it goes to. aan is for sls and the mln is for deville. as long as the conectors are the same thair should be no problems. i changed a 4t60e out of a 95 deville and the id tag was difrent then the replacement transmission id tag and a year later its still driving so . im gonna say ya it should be fine

only northstars have the 4t80e . the 4.9 needs the 4t60e

your shift cylinoids mite be out or the clutches may be burnt time to replace the tranny it sounds like could be the valve body or real low on fluid check the fluid and smell it if the fluid smells burnt chances are its cheaper to just replace the tranny
