Hi,
If I understand, there is no reverse, correct? Next, have you checked to make sure the shift linkage hasn't come apart?
Next, there is a chance the problem is internal, but I'm a bit confused why all wheels would have locked. If it is internal, I suspect it is related to a broken retainer in the forward clutch pack that is allowing the clutch to remain engaged at all times. Hence, trying to go forward at all times regardless of gear selection.
When you place it in park, does the vehicle move, or does it simply load the engine down trying to go forward? Next, when it is in reverse, does it feel like it is fighting itself?
Let me know. I suspect we will need to remove the transmission pan to check for any damaged metallic components.
Take care and let me know your questions and as much as you can think of that could help me. Also, let me know if there was a bang or any noise when the wheels locked.
Joe
