Re: Parts on order...

Hey Frank, yeah, I assumed there was a temp sensor already in the tranny (hence the TRANS OVER-TEMP light) but I'm not sure if a standard temp gauge could read from it.

I'll have a look and see if the Innovate LM-2 datalogger I have can read the temps from the OBD-II port or not but that isn't something that is going to be plugged in at track days etc, hence the gauge idea. If I can find a gauge that can show various info from the PCM though that would be superb.

Re: Parts on order...

Could not find a lot of info regarding the tranny temp sensor Marty. It seems to be a normal thermistor, but you could possibly affect the temperature signal to the TCM when you would use the signal for a separate temperature indicator.

Re: Parts on order...

Got the new solenoid and shift kit installed last night! Special thanks to my Dad, I would have been in trouble without him (and his much more complete tool set).

Took a few pics of the progress, but spent most of the evening covered in transmission fluid. Here's a pic of the parts etc, layed out:


Here's the bottom of the transmission after the pan and sump filter are off. I was surprised how clean it was inside, especially given the way I drive... Just a light coat on the magnet otherwise the pan was clean.



Next we pulled the valve body. Of 6 8mm hex bolts, 5 broke loose pretty easy, but one rounded... F*ck! So we had to carefully grind the head a bit, and then my Dad used a flat bit on his air impact and was able to break it loose. Turned out much better than I first hoped, and the local hardware store and an exact mach bolt!



Here is the valve body off on the bench. The solenoid is held on from the bottom by 15 torx screws, which all came out nicely.



Once that was off we swapped out the old shift plate for the new one, as highlighted by the circle:



After that, everything was bolted and torqued back together, and the accumulator plate came off to install the upgraded rings and springs from the Transgo kit. Very straight forward to install, just follow the instructions that come with it! I was happy to see that the pistons and cylinders in the valve body all looked almost brand new, no scoring or anything!

No more pics at this point, I was getting too excited to get everything back together. Valve body bolted right back into the transmission, new filters installed, gasket and pan installed, and then 6 fresh quarts of amsoil ATF dumped in! She shifts beautifully now! No chance I will end up lying in a ditch now Dave! The first few seemed a little rough but she settled in pretty quickly and I'm an extremely happy camper. Took about 3.5 hours total so not too bad for 2 guys who had never gone this far into an automatic transmission before. Now I just have to check if my backup light circuit is working again! Thanks to Dave for recommending the Transgo kit, and Frank for a source on the solenoid. Ordered everything Monday afternoon and it all arrived by Thursday morning, very prompt. What would I do without this place?!

Re: Parts on order...

Good to hear it all worked out well Aaron. Did you see any difference between the new and the old shift plate? I compared them both, but didnīt see any difference in between them. I installed the new one either way.
Iīm still not so happy with how my tranny works. It shifts ok, but the fluid changes color from the normal red to a more blackish. It was like this before i changed the solenoid pack, but seems it didnīt change anything. The fluid doesnīt smell burnt, but i have no idea why it changes color that quick. I wonder if there is something bad going on in the tranny, or that the fluid, recommended by the rebuilder, is the culprit. There is also a slight fluid leak from the torque converter area, which drops exactly on top of one of the pre-cats and burns away. I wonder if the rebuilder had put new seals on the torque converter axle after he had to pull the tranny for the third time...............
At least seems that there will be some work to do for me in the (near) future.......

Re: Parts on order...

I could not see a difference in shift plate either, but I took their word for it and installed the new plate. He put new filters in the transmission right? Don't know what to say about the fluid getting dark right away, my fluid was replaced a year ago and still came out fairly red. He used a mopar atf+4 equivalent right?

Re: Parts on order...

What he used was a synthetic fluid, but i think its not a real equivalent for the ATF +4. He used it on other chrysler products with the same tranny and said it was working fine. I don't recall how the fluid was looking soon after the rebuild, but at least 5 weeks later it started slipping again and he found a break in the solenoid block seal plate, causing the pressure to drop and OD clutch to slip.
The fluid is so awlfully expensive that i just can't afford a flush again and then finally finding out that something is wrong inside the tranny and do it all over again. I will try to find a real specialist overhere (which is almost impossible to find) and see what he will say. But the tranny has to be removed anyway to find out where the fluid leak is coming from.
The colorchange of the fluid seems to be coming from clutch material, that at least is the only black stuff in there what i can think of. But i didn't experience any noticeable slip. Also don't know when the fault code for a slipping clutch will be set. From previous experience at least it seems to come at the moment the jeep is not driveable anymore = too late.

Re: Parts on order...

Glad your happy Aaron. I knew you would be. Frank maybe it's the Amsoil like you said. Maybe try something else and see what happens.Gonna take a couple of changes to get it all out though unless you get it flushed.
