1999 Dodge Van, 48RE trans no shift from 2-3rd or 4th
Occurs when the gas tank has less than 1/16 basically on empty.
I would drive towards work no shift would occur.
Stopped at gas station on many occasions..
When I put in gas the transmission would begin shifting again.
Few times I stopped w/ out putting in gas.. problem continued.
So how can the gas tank, gas line or ??? have anything to do with the transmission shifting.
This went on for 6 months Yes,,, just keep gas in it!!! We’re all smart.. but the question still bugs me.. and then one day speedometer went to 0, and no longer works, the transmission will not shift from 2nd.. up to 3rd or 4th and I took it to a tranny shop that found no code issues but suggested that is was the governor sensor, tranducer/solenoid and trans speed sensor..
So.. I disconnected the battery for a bit and will check and replace all fuses that might have a relationship. Seemed funny that the gov sensor, solenoid and speed sensor all went out at once.. I think the tranny shop is guessing and recommending all 3 replacements..
But.. I still wonder if there is a fuse or something else I should check first..
I have purchased the sol/transducer and two sensors and am ready to replace them also.
Before I'd suspect a clogged anti-drainback valve in a 545RFE, I would sooner suspect a clogged return filter.
By the way, the 545RFE is a fully adaptive transmission, which means it adjusts shift schedule and shift points dependent on driver and load behaviors. While pulling the trailer, it relearned a shift schedule for that type of driving. Now that the trailer weight has been removed, it probably thinks there's still 7000 pounds of weight to pull around. Driving for a period of time without the trailer weight should readapt to the latest driving behavior.

What I'm trying to do using this forumn, is take the info to a tranny shop and use suggestions to possibly curb them from ripping me off with a new tranny. My truck isn't getting any better or worse, and I commute 60 miles a day for work, so I can either keep doing it or slowly go crazy not being able to accelerate like I want to. Can you give me a bit more info on what you did?
And another thing is when i put the gear selector into 2nd i cant gain speed the rpms just increase or it downshifts into 1st...while driving....if i take off while it in the 2nd postion it won't shift out of 1st
mine shift at 3 to 4 grand but it shifts even if i dont let off the gas
trans was operating just fine when it stopped shifting into drive, was stuck in second. i tried manually shifting back and forth but no change, tried changing trans fuse under the hood. i check all the connections into the trans and all appeared to be fine.
today i pulled off one conection at a time and checked the trans operation. when i pulled apart one conection...started up and drove with the connector off.... the trans now operates in every gear... only i have to shift through them manually.
the connector that i pulled off was on the drivers side a little above the center line and set back on the tranny a little. it was a circular connection. (there is another connector on the same side but it is lower and towards the front is a square connetor)
thanks in advance for your input!!!
the "circular" connector i referred to is circular on the inside and almost square-rectangle on the outside. there are ten wires going into the connector. this conection is above the trans oil pan, there are two connections on the drivers side and this is the one that sits higher and further back.

they give answers to question.... they acually respond!!
Start with taking off the lower pan, the governor is the round solenoid on the passenger side of the valve body. It has a metal retainer around it with 3 bolts with 7/16 heads and two screws with torx heads. Remove the bolts and screws, remove the retainer and remove the governor solenoid. Remove the last 7/16 headed bolt in the governor plate and remove the governor plate. After you remove that you can then remove the 3- 4 shift solenoid and the TCC solenoid. Check the screens on all three solenoids. If they have metal shavings or clutch dirt on them you can either try cleaning them or replacing them. I'm not sure about the 3-4 shift and TCC solenoids(they are built together) but the governor solenoid is about 100 dollars. So it is worth (if you have the time) to try cleaning them and reinstalling them to see if they work. Tighten the 7/16 headed bolts to 120 inch pounds and the screws to 35 inch pounds. Install a new filter and clean out the pan. Refill the trans with ATF +4. If you have any more questions, just ask
i followed these instructions... but...
... i couldn't afford the parts so i went to the local wreakers.... they wouldn't sell the parts as they couldn't test to be sure they worked....so i went to a 1998 cherokee 4x4, mine is a dodge 1500 series 2x4 but the trans looked the same..., i removed the governor, governor plate, 3- 4 shift solenoid and the TCC solenoid and also the speed sensor. i have NEVER looked inside a transmission but due to the ecellant instuctions posted here... i did it... took my about 10 hours with the trip to the wreakers.... my truck shifts through all the gears... thanks... saved me a bundle
if you think it is the trans computer... go to the wreakers.... match the numbers on yours to assure proper part number. bring your truck and change it in the lot... it's an easy change i looked at mine.
you also need to read my question and my self response. found at fixya.com. the instructions i found there were amazing.
read #1618 i think that is the one... follow it back
i tried putting gas in my truck but wasn't so lucky.
this is the best solution that i have found on the net..

this came from fixya.com ,search 1999 dodge 1500 4x4 won't upshift... should find the original response and detailed instructions...
i hope this helps
also if you crawl under on the drives side of the trans pull the middle connection off... you should then have all gears but will have to shift manually....
