Re: transmission solenoid pack problems

Just to rule out the Transmission Control relay to be the fault, you could swap it with the auto shutdown relay. Both are sitting in the PDC under the hood. Disadvantage is that if the relay IS the problem, that your engine will shutdown. So you should only try this as a test, knowing that the engine could shutt down at any moment.

Also after codes ran today it ran perfect all the way home. I'm convinced almost that I have received a bad solenoid pack.

Re: transmission solenoid pack problems

The P0750 and P1768 you had before already, the P0755 and P1733 are new.
The P0755 is shift solenoid B malfunction and P1733 is 4C pressure switch sense circuit, indeed both have to do with the solenoid block.
But it seems that the solenoid block change didnīt do any good for the L/R solenoid (P0750). Eventhough the new (remanufactured) block can have a problem(s), it would be a coincidence that it has a problem with the same L/R solenoid.
The new problems could be from the new block. I would recheck the large connector on the block to be sure that its completely inserted and the lock lever is in its locking position.
Also remove the large connector on the TCM in the engine bay (the one with the bolt in the center) and check for moisture and/or corrosion on the pins. Use some electrical contact cleaner to clean the pins well and some shop air when available to blow it completely dry (check both sides, connector and receptacle).
I would also check the cable bundle as far as possible, also under the jeep, for eventual chaving or sharp bends.
Then clear the faults and testdrive to see if the faults come back.
Do you have guarantee on the remanufactured block? A new block cost around USD 280 (www.electricaladvantage.net), but your problem could also be caused by a bad TCM.

I thought I was receiving a reman pack but it was obviously a used one When I got it. (Was supposed to even be black plug but wasn't) the guy that owns the place won't even ansew his phone. I got under there and made sure it was connected well yesterday. I'll look at the TCM might take me a bit to locate it.

Just removed the plug from TCM there are some traces of moisture in the lower half of it I'm going to blow out out as good as I can I don't have contact cleaner at the moment.

Almost the whole time it was parked the week I waited for the solenoid pack it did have a good chunk of snow and ice on the hood right over where the TCM is mounted.

The problem is that you can never rule out any possibility and start with the simple (free) solutions first. You can ofcourse just change parts, but that can become an expensive excercise. It would be a sad story to discover, after changing several parts, that the solution was something simple.
If you would decide to change the solenoid pack again, the address i gave you before is a thrusted one. I bought my solenoid pack there some time ago and they only work with OEM parts for a good price.
