2005 Dakota Transmission issues
Howdy Do!
We have our old crusty wondertruck: 2005 Dakota SLT with the 4.7. Up until recently the only issue we've had is vanishing brake fluid (think we need to replace the master cylinder once it gets warmer)
So the other week we had to do a 'dinner date' with the wifes boss. Haven't had the need to drive it much, as I work from home. She fired right up. And I noted the 1-2 shift was perfect. 2-3? Very harsh. After dinner it was the same way. I checked the fluid- Still bright pink and perfect. Slightly low (still about 1/2" above the full cold mark after driving). We did add about 1/2 qt and that's got the level between the cold/hot mark-just right. Decided the other day as we needed to move the trucks for plowing to connect the scan tool.
Transmission line pressure "Low". I pulled the live data and it was 'calling for' 120PSI and only producing 35-40PSI as per the sensor.
Had to relocate it again yesterday and it had 2 transmission codes 'stored' Transmission line pressure 'low' and the other one Transmission line pressure 'high'?!? Live data: Called for 120PSI. Sensor read 118-119PSI. So it fixed itself---NOT!
This is really getting strange. I went to put it into gear. Usually there's a very small delay on going into reverse or drive. This time it was about 4 seconds before it would engage 1st or reverse. Same result if I shifted to manual first gear.
Would this all be related to the line pressure sensor starting to fail? I don't dare drive it, as while it was rebuilt about 80k ago- It's been rock solid and the fluid looks perfect. I'd rather not risk damage due to slippage.
Any ideas would be fantastic. As we're up in Fulton, NY- No chance of doing anything under the truck as we've got over 3' of snow to contend with... Might consider having it towed to a shop-but would kinda like to get some idea on what could be going on.
Thanks!

Oddly enough I have a pressure gauge set that does engine pressure and a higher gauge that we use for transmissions.
Sadly the 'barn' I tinker with cars in my spare time is current covered in about 3' of snow. That's where the tools and my extra supplies (jacks, stands, etc...)
I'd hate to have the Dakota sit for a couple more months of this snow mess
Figured if the pressure sensor was defective it might cause some of the related issues.
