Exclamation Shoud I be concerned???

Hey Guys...

I had the truck loaded up with about 16 bales of hay/alfalfa and tried climbing a steep residential road in 2nd. I approached the hill very slow (no momentum) when I noticed the truck was not moving forward even though the rpms was up to 2k. I don't think the rear wheels were breaking lose, so I down shifted to 1st, and the truck crawled up the hill.

As a test, I went back (unloaded) and purposely stopped on the same hill with the truck in 2nd. I gave it some gas, and the truck didn't move forward, but when I downshifted to 1st, it crawled right up.

Usually, I have some momentum going up the hill and don't notice any problems, even in D.

Any thoughts? Is this normal (never owned an automatic before)?

Sounds like the clutches for second gear are worn out, i think you are going to need a rebuild.

Just another bit of information... I purchased the truck with 135k miles and the PO mentioned the tranny has been rebuilt twice (not sure about the details of the work done). The second time he took it in, the shop also put in a heavy duty torque converter.

Just put it in D and try to pull the hill. 2nd may be too tall a gear for the hill.

That's what I was thinking too. I'll have to try stopping on the hill in D, and see if I could make it up.

I seem to remember my Jeep with 4.56 gears in 2nd gear wanting to die if I went too slow.

You shouldn't be in 2nd loaded down like that, it is very hard on the trans, it will overheat quickly. Either shift it manually starting in 1st, or leave it in drive and let the pcm do it for you.

what he said. remember, when you shift into 2 with an auto it stays in 2, even if you come to a complete stop it will start in 2nd gear. if you floored it and only got 2k rpm, then that is the stall rpm of the torque converter. if the 2nd clutches were slipping it would wind higher rpm than that. you just had too much load/too steep a grade for a 2nd gear takeoff.
