 Subject: Transmission control solenoid

Message:
The other day my 99 Dak v6 3.9 with the 42re auto-transmission stoped working. It would not engage into 2nd gear or higher. I could only go about 10 miles per hour and reverse was fine. This happened out of the blue. I was about to take my trans out for a rebuild but I was told not to. A guy walking by saw me working on my truck and was curious to what I was doing. He said it was my Transmission Control Solenoid. He said I would be wasting my money and time if I continued. There was soft sludge on magnet but I understand this to be normal. Anyone with an idea please let me know. Thanks! James F.

Its sounds like you have a burnt valve body. Just as well plan on buying a new trans.... To keep this from happening again add an inline cooler. After you get the transmission out flush your lines and the cooler at the bottom of the rad.

Mine did that once. But I replace the sensor (don't remember what it's called) on the side of the tranny. Problem fixed - shifted fine.

Shane you are absolutely right! It is the transmission speed sensor which cost about 23.00 and is located on the tail end of the transmission. I was told by a supposedly trustworthy mechanic that there were no bad sensors and that it needed a rebuild. Thank God that fellow stoped by and made me think twice about what I was doing! Even after reading diagnosis all over the internet and the Haynes manual and that damned mechanic none indicated it would be the speed sensor. It makes me wonder how many people get told they need a rebuild when all they need is a little part. By the way Shane that fixed the problem just fine!
I learned a valuable lesson on this and that is to take a similiar approach as you would with the engine. Droping the oil pan and observing the condition of the fluid and whats in the pan will be the indicator of what may be wrong. If there are no hard pieces of metal it is probably or most likely electrical or external in nature. Don't trust your mechanic until maybe a second opinion.
This needs to be added to the Haynes and other manuals on trouble shooting the automatic transmission.
Transmission will not engage 1-2nd or 2nd- 3rd.
1. Fluid level check and change
2. speed sensor check and replace
3. control solenoid check and replace
If that doesn't solve this problem then use a certified trustworthy transmission specialist or mechanic if one exists.
No offense to anyone who posts on this site unless you are guilty as over charging your own customers.
Merry Christmas!!

kpg it just screws out. I used a cresent wrench or and open end wrench if big enough. The sensor has a spark plug like design. It only takes about 20 seconds to take care of it.

look up cascade transmission ,they have videos of the sensors and problems with the 42,44,46, [this will show you where and how ,to see if your up to it ..] if your a so so mech and have the common tools you can replace those .also be aware most problems are senors ,BUT some are not receiving the correct info from the sensors .[busted wire ,bad ground ] also check your downstream 02 sensor wires ,are they frayed broke ? this circuit also has voltage to the Governor sensor ..which operates the shifting process ,[not enough ,or improper voltage ] so the trans doesn't know how to shift ,.this can be sporadic depending on how bad the break is .although the sensors are the problem ,, dont be disappointed if you replace them and it wasn't the problem ... also check fuses that supply voltage to the pcm and trans .there are plenty of good sources on the net to help you figure out what you need , research to sites specific to the trans you have .got my 42 going ,but still having issues will report what i find .hope this helps

Ok, call the bone yard to come pick it up.
I bet you did not change the transmission & filter every 30,000.
