1998 with 5.9 and 46RE transmission with 155k miles. Transmission was rebuilt at 85k quite a few years back.

Pan was corroding and starting to seep fluid. Replaced the pan, gasket, and filter last spring and have less than 10K miles on the new fluid.

This week, it started to not shift from 1st to 2nd normally. It will keep climbing in RPMs until about 3K and then shift if I let it. But I usually let it get to about 1800rpm, lift off the gas and it will then shift to 2nd. It shifts normally from 2nd to 3rd and 3rd to 4th.

Thinking 1st was slipping, I put int in Low and took off. It feels normal, and pulls fine even if I get over 3 k rpm. I can manually shift through the gears and everything feels fine.

If it was a band adjustment issue/slippage, would it slip when left in Low?

Or does it sound more like a Governor Pressure Solenoid & Sensor issue?

A 1/8th adjustment on the tv cable should solve the shifting issue, as mentioned. When the transmission gets serviced make sure the bands are adjusted properly.

All the experienced folks will jump straight to the governor pressure solenoid and sensor kit. Before you do that, fashion yourself a test gage and hook it up to the governor pressure port, jack up the back wheels, and then read the governor pressure at various speeds. It should be 1 psi per mph, so it should read 20 at 20 mph.
What I've found can cause this:
- Governor pressure solenoid screen plugged with debris
- Governor pressure solenoid bad
- Speed sensor bad
- Controls screen plugged (it's in the channel plate)

On my truck, the culprit was the controls screen. I ended up changing the other stuff before I found the screen had split and trashed the valve body. New screen and a thorough cleaning got it back to working.
Put yourself an external filter on it when you go back together. Your transmission will thank you.

The real beotch of this whole thing is that a fluid change will cost you $30-40, so if you go transmission diving and don't get it right the first time, you're out $40 again for fluid. You could go armed with everything, but then you are just throwing money at it unnecessarily. My money is on the $1.69 screen and clean the debris off the solenoid screens.

Wow!
I didn't think it had been that long ago that I started having the shift problem. Yesterday, I dropped the tranny pan and found the front band support anchor laying there. I removed the valve body to put the anchor back in and adjust the band. Well, the band will tighten with the ends about 1/4" apart. Closer inspection shows that there is no friction material left on the front band. That is how it became loose and shifted, allowing the anchor to fall out. Since the truck is driveable, I decided to put everything back together and ease my way to the shop to have my tranny rebuilt. Once everything was back together, it will no longer start in park, but will start in Neutral. I am thinking that the shift linkage just needs adjusting.

Does anyone know how to adjust the shift linkage?

The 2001 Dodge Ram FSM shows how to adjust the TV cable for the 46 trans. If I can find the 46RE on the Durango, I'll post it up, but the Ram is similar
