4L60e Trans problem
1996 Siverado four wheel drive not working and transmission has no forward gears but does have reverse. If I pull the 10amp trans fuse to go into limp home mode and by putting gear selector in overdrive or drive, I have third gear only and also have reverse. There is no check engine light unless I pull fuse. Scanner only has PO; 753, 758, 1860, and 1886 only when trans fuse is pulled. Has anyone seen this kinda problem before. I searched wide and far on the web and cant seem to find this kinda problem anywhere. Your advice would be greatly appreciated.

If at first you don't succeed, chances are, you are using too small of a cheater bar

Have you checked the fluid level?
I know that may be a silly question, but it is the most common problem in an auto box.Ray

- P0753 1-2 Shift Solenoid Valve Electrical (Shift Solenoid A Electrical)
- P0758 2-3 Shift Solenoid Valve Electrical (Shift Solenoid B Electrical)
- Transmission runs only in 2nd Gear. This is known as running in LIMP IN MODE.
****Below is a G.M. Technical Service Bulletin...that maybe able to help, its regarding Trouble Codes....P0753, P0758, and P1860,
Bulletin No.: 01-07-30-002E
Date: September 23, 2005
TECHNICAL SERVICE BULLETIN
Subject: Malfunction Indicator Lamp (MIL) On, Transmission Stuck in Second or Third Gear, Instrument Cluster Inoperative (Verify and Repair Source of Voltage Loss In Transmission Solenoid Power Supply Circuit)
2006 and Prior GM Passenger Cars and Light Duty Trucks
2005-2006 HUMMER H2

With 4L60-E, 4L65-E, 4L80-E or 4L85-E Automatic Transmission (RPOs M30, M32, M33, MT1, MN8)
This bulletin is being revised to update model years, add additional models and add additional diagnostic information. Please discard Corporate Bulletin Number 01-07-30-002D (Section 07 - Transmission/Transaxle).
Some Customers May Comment on One or More of the Following Conditions:
....The Malfunction Indicator Lamp (MIL) is ON.
....The Transmission is Defaulted to Second Gear (4L80/85-E)
....The Transmission is Defaulted to Third Gear (4L60/65-E)
....The Instrument Cluster is Inoperative.
One or All of the Diagnostic Trouble Codes (DTCs) P0740, P0753, P0758, P0785, P0787, P0973, P0976, P1860, P2761, P2764 and P2769 May Be Set Depending on the Vehicle.
The most likely cause of this condition may be a loss of voltage to the Transmission Solenoid power supply circuit. This condition may also be the result of an incorrect installation of an aftermarket electronic device such as a remote starter or alarm system.
Important: If the vehicle is equipped with an aftermarket electronic device and the DTCs are being set when the device is being used, verify that the appropriate fuse is being supplied battery voltage during operation. If voltage is not present at this fuse, these DTCs will be set due to lack of voltage at the solenoids. This condition is most likely to occur with an incorrectly installed remote starting system. If this is the case, refer the customer to the installer of the system for corrections. ANY REPAIRS DUE TO AFTERMARKET INSTALLATION OF ACCESSORIES IS A NON-WARRANTABLE ITEM.
1. With the ignition switch in the RUN position, test for battery voltage at the circuit fuse in the transmission solenoid power supply circuit. Refer to the appropriate SI Document for the transmission solenoid power supply circuit information.
2. If battery voltage is present at the Fuse, inspect the Ignition voltage circuit between the fuse and the Transmission for possible opens.
3. If battery voltage is not present at the fuse, test for continuity between the Fuse and the Ignition Switch. If NO continuity is between the fuse and the Ignition Switch, repair the open in that circuit.
4. If you have continuity between the Fuse and the Ignition Switch, the most likely cause is the ignition switch. Replace the Ignition Switch using the appropriate Ignition Switch Replacement procedure in SI. Refer to group number 2.188 of the parts catalog for part description and usage of the ignition switch.
