What is the most common cause of failure in truck standard transmissions?
Leaking or Low Transmission Fluids
Any sign that the transmission fluid is low due to leaking should be taken seriously and repaired quickly. Low transmission fluid is the #1 reason for transmission failure and leads to major damage to the transmission if not caught quickly.
How do I reset my 6L80E transmission?

Can torque converter cause transmission problems?
A damaged fin or bearing in the torque converter can cause hesitation in the transmission shifting, or the transmission to slip out of gear entirely. This is because the engine torque is not being efficiently converted into the hydraulic pressure needed to shift gears within the transmission.
Is the Hydra Matic 6L80 a good transmission?

What do check balls do?
One of those valves designs utilize a check ball, which allows or blocks fluid flow. Fluid pressure causes a check ball that sits in a pocket to block and unblock on orifice that fluid is flowing through or trying to flow through. This controls the timing and redirection of fluid flow.
How many check balls are in a transmission?
There are 14 steel checkballs in the lower portion of the valve body (Figure 2).
