This is my first time on this awesome website. Purchase 03 2500 Quad HO with 37K. Change all fuilds and drop tranny pan vice flush to R & R fuild. Nothing out of the ordinary in the filter or pan.

Problem: After driving interstate speeds then stopping for a short time 10 -15 minute, when driving next the tranny shift's are hard, both up and down 2nd to 3rd and 3rd to 2nd. This was the same case before the fuild change. I have search this website for more info.

I would appreciate any help. Bad Torque converter?????

Hi, Okie,

I'd have a hard time deducing that. I have a 2500 '03 also, and I'd only describe the shifts as hard or firm when the transmislsion is at low speeds. Under WOT, it slips so much that I avoid it.

Around town, it's formulaic: the shifts at part throttle seem to be based on speed and nothing else.

Hard shifts are GOOD. Mushy shifts, like WOT on my truck or TC/gear indecivesness, are not good.

When climbing, I wait for it to drop out of OD or loosen up the TC and start "hunting," and then I turn it off.

I will now back off and let other more experienced members add their comments.

Thanks for the reply. It's diffinently a hard shift.
