46RE Issues accelerating from a stop
1997, 5.9, 46RE, 4x4
Started having problems with my transmission about a week ago. Hopped on the forum and spent about a day reading all I could. Got a parts list together and spent a day under the truck.
Here's everything I did:
- Replaced governor solenoid and sensor
- pulled valve body, sprayed out with carb cleaner, and installed a TFOD-Jr. Shift kit
- Adjusted front and rear bands per specs in service manual
- New filter and Valvoline ATF-4, and a bottle of Lucas transmission conditioner
Got it all back together and test drove. No change in operation. Frustrated to say the least.
Here are my symptoms:
Seems to be starting in 2nd gear from a stop. If I ease into the throttle I can get her rolling. Stomping the accelerator from a stop gets me nowhere. RPMs rise, truck sluggishly rolls of the line. If I let off for a moment it will grab 1st gear and usually take off. I can manually put the truck in 1st gear when I come to a stop, however this exposes another problem. Again, easing into the throttle, the truck will operate like normal as I shift the lever up into 2nd and finally Drive. However, with the shifter in 1st gear, if I stomp the throttle the drivetrain shakes / shudders violently as it takes off. Tapping the brake pedal has no effect on operation.
Once up to speed, everything works great. TC locks when it should, tranny shifts into overdrive, and will drop gears like normal when I lay into it.
What is going on??
Any help is greatly appreciated!
Edit: I found a broken OD accumulator spring inside the valve body, and it was replaced by a spring included in the shift kit.
