Well unless it throws a code for a transmission solenoid how does he know that's the problem? The ZF is not known for solenoid problems but it does happen.
What are the codes now? Has the 741 code remained or not? Still could be the TQ?
How many miles were on your box before the rebuild? We just recently learned from another vendor that the valve bodies do wear and sometimes require replacement.

Hi tbird6, the P0741 code is consistent.I had it cleared and it came back on within 5 minutes. I didnt even drive 2 miles before it came back on. The car had approximately 85k miles on it before the rebuild. I don't know why they're replacing the solenoid, which is what has me worried. I asked them about it and they said they'll replace it and go from there. The car only has 8.5k miles on it since the rebuild. Shouldn't the valves been replaced during the rebuild? Forgive me if that's a stupid question, I 'm not very mechanical...yet. I'm thinking they're going to try and clear the code hoping the warranty will expire before the warning light comes back on. Then they can charge me for the repair...I checked into TQ's and they're around 1.8k for a new one. So I'm thinking he's trying not to replace it if he can have me pay for it. I don't know what makes him think I'll take my car back to him if the tranny does fail again...I'm not a fool..

No. The shift solenoids are only replaced when they are bad. Same with the valve body.
I think you need to focus on the TQ. That is what the repeatable code is pointing to. You did the right thing by clearing the code. It came right back so you have a hard failure. Fix this first it won't go away.
Maybe push some more for a replacement TQ? Do you have a written estimate when you agreed to get the transmission rebuilt? It should have a list of what they will be doing to the transmission. I have never seen a rebuild not include at the very least a rebuilt TQ.
Think about it from the shops point of view. Why would they risk a $7K rebuild and not replace it? If they won't go for a replacement maybe compromise and split the cost with them? Not ideal but you have already spent the $7K. You won’t be getting it back!

You have a point, but I just can't see giving them a dime after a 7k rebuild only lasts 8.5k miles!! I will push to have the TQ replaced. Since it is a hard failure, replacing the solenoid shouldn't do anything, correct? The gearbox fault and P0741 codes should come right back like they've been doing. The invoice did include the TQ. I have record of that.

The P0741 will be caused by ANYTHING that causes a difference in engine speed and input shaft speed when it thinks the TCC should be applied. That could be the converter itself, the solenoid(s) that control the TC Clutch, or a leak in apply pressure. The latter could even be a failed/split "O" ring on the trans shaft, or in the Mechatronic Valvebody gasket to the case.
I would advise staying on the repair outfit to resolve it before the time is up. So, let them replace the solenoid if they believe it's the culprit. Just don't dilly-dally. If that doesn't correct it, they'll still have time to take another tack.
EDIT: I should add, document everything. Every contact, conversation; and ask that everything they do in attempting to correct the fault be written and explained clearly on any work order or receipt.
Good luck!

Thanks...I absolutely will do that.

Hi tbird6, so I'm assuming if he's trying to replace the shift solenoid(s) that's a very bad thing. Let's say for argument sake that he is replacing the shift solenoids, what should he do instead of that? What should I be looking for or cognizant of?

Just an update. You guys were dead on as always. He called me on Tuesday, stated he'd replaced the solenoid and it didn't fix the issue so he's sending the torque converter out to be rebuilt. He stated he had sent it out originally, but obviously something went wrong. I am somewhat uncomfortable with rebuilding the TQ again, but I don't think he'll be willing to replace it at his cost. Oh well, hopefully if they have to do it again, maybe they'll get it right this time. Thanks for the help forum!!!

That's good news! At this point in time I don't think new TQ's are available and all we have are rebuilt units. This is not bad as you are the first person I know of that had a rebuilt unit fail. But to be far it looks like it was bad as installed so it was not properly rebuilt in the first place.
One more request? The shift solenoids are in the valve body but I am not sure of the exact location of the TQ lockup solenoid. Can you post back a part number or description of which solenoid was replaced?

Absolutely. I should be picking up my car either tomorrow evening....at the latest, Tuesday. I'll post it then. Thx.
