Hello All,
I think this is a transmission pump issue, but I suck at transmissions and need opinions.
2004 kj auto - was running fine. Then suddenly one day starting having the following issue:
Start the car, no noise at first. Drive off just fine. No problem shifting. Soon (like 2-3 min later) start hearing fairly load grinding noise, but still shifts fine. Then about 5 to 8 min in, the whine suddenly shuts up but the engine spins and the gears are no longer engaged, as if the car is in natural. This is a repeatable process, let the car sit, try the next day. Same exact symptoms; runs fine for a couple of min, then starts to fail. As if low on fluid.
No codes. Fluid level is just fine, does not smell abnormal. The whine revs with the motor regardless of gear.
Now, I had heard this might be a clogged line, so I bypassed the trans cooler by simply adding a tube to the trans line to the in and out of the cooler line near the front to the car. This made no difference in the above failure. However when I put the trans cooler back on-line I noticed that the piece of tubing was bone dry, as if no fluid had ever made it that far.
So would this make sense that this a trans pump issue?
I have not pulled the pan yet. Could this even be a clogged filter? (I've never heard of such a thing).
