Glad that I could assist. I finally heard from the owner of Doghouse and he assured me that the parts will fit my application. They should arrive tomorrow and I'll know tomorrow night if, the codes (P1762 & P1763) are solved. I did install a drain in her tranny pan to make this a tad less messy next time I drop it.

Thank you for the great write up fireman33!!

Keep us posted. I unfortunately read this too little too late and because of timing had to have somebody pay to fix mine with the normal parts. Picking it up today. $485 later........ Pissed............ Second time in 30k miles.

Thank you Chrysler for the wonderful 42RE.

Not quite a month yet but, still no codes on her WJ. It shifts and performs nicely. This was my first experience inside an AT, outside of changing fluid and filters. This write up was instrumental in convincing me to do it. I hate all heep electrical and fuel connections and I was worried about screwing up the electrical connections like I have in the past with my TJ. A little research and this worked nicely. Don't beat on the 42RE to harshly. I have heard the same thing about our 42RLE and wonder how much difference there is between the two. I have 115K on mine and hope that they are as easy to work on as the 42RE is.

Not quite 3 months later and the P1762 has reappeared. There have been some complications that have occurred since my last update. Her radiator took a dump approx 2 months back and allowed the ATF and coolant to mix in the cooling system and the tranny. Replaced the radiator (what a major PITA for you guys to replace), hoses, water pump, t-stat and belt. Called a couple of sources, that worked in tranny shops, and they advised to flush the tranny and then do it again in 1K. It took 2 cases of ATF to even make the ATF begin to look normal and not have the "Pepto-Bismol" color and consistency.



I did the flush again at the 1K mark but only shot a case through the system. I could never find the 42 RE's recommended capacity through the FSM or Google but, recently was fed a figure of 14.8 QTs from Advance Auto Parts. I know that coolant/water is very bad on trannys so, I really do not know what this all has to do with the reappearance of the P1762. I cleared the code and will post up any additional info as I discover it.

When it starts off, in what feels like 3rd, that means the trans is in "safe mode". It usually relates to an electronic issue with the trans like a solenoid, sensor, or trans related circuit.

Make sure you translate the code and check everything related to that code to help you pinpoint the root-cause.

If it's a more mechanical-related issue with the trans, like bands or clutch wear, you usually won't get a code. If you don't repair the problem causing the safe mode and fault code, large mechanical issues (see catastrophic failure) will occur.

Man thanks for posting this! AAMCO Transmissions tried to charge me $420+tax to do this, I priced the solenoid and governor pressure sensor they both equaled about $100-150.00 for both of them. Ill save about $300 doing it myself! Im going to try this this upcoming weekend. Any tips or suggestions?

All I can say is make sure you keep everything clean. Don't wipe down any parts with rags or towels because the smallest hits of debris can cause damage later on.
The trams fluid is expensive, but buy one extra quart just for cleaning. Anything that comes out of your trans "wet" should go back in wet. Use only new/clean trans fluid to clean your parts in. I usually buy a throwaway foil cooling pan from the dollar store, put some clean fluid in it, and use it just for pre-cleaning new parts before they go into the trans.
Also, when you buy a filter/pan gasket set you will be better off getting the more expensive one that is not folded in the box. The folded cork ones are just a pain in the *** to get right. Also, follow the torque specs closely on that pan gasket. They will leak really easily if over/under torqued.
When you refill the trans, follow the procedure to a tee. At final top-off, the engine should be running and you should row the trans through each gear for about three seconds each while parked. Then go and check for the accurate level.
It's not too hard of a job, but the details are important.
Good luck

Cascadetransmissionparts.com sells a kit for $199 that includes the 2 solenoids, (the beefier BW one), plus, a new tranny output speed sensor, a new beefier accumulator spring, 2 new gaskets ( the tranny pan and the one for that little plate you need to remove), plus a tranny filter. Good deal IMO for what you get.

@autojunkie where can I find a more sturdy gasket? I purchased a filter and gasket from autozone for about $7. The gasket that comes in the box is sort of cheap looking. Any suggestions on where to purchase a better one?

Also where can I find the torque specs for the 42RE? Can't find anything online for it. Also, does anyone know if I have to adjust the bands on my specific model or not? If so, does anyone know how to do it?
Thanks

I highly recommend getting a Factory Service Manual. They are available on disc via ebay for about $10. It will be your bible and answer pretty much every question you have.

@nickblack I just purchased one from autozone! Spent 24.99 for it, hope I can understand it. I'll take pics and post them to the blog and let everyone see how it goes

I would get that kit that someone posted under my last post. The gasket looked like a good quality.
You shouldn't have to adjust the bands. Doing that can, if done incorrectly, can cause more problems :/
The manual from Autozone might have torque specs for you, but the factory repair manual is much more thorough and easy to follow.

@dnovak It sounds like low fluid. Make sure your trams is nice and warm when checking the level (normal operating temp). Row through each gear for about three seconds each, put it back in park (with the engine still running), and check the level.
Try and get it as code to full as possible and do not go over. Even a little bit.
Each time you add fluid you have to go through the same procedure to get an accurate reading on the dipstick.
