p0730 and p2703 codes help!!

Trans is flaring shifts from 3to4 and 4to5. Goes into limp mode and will shift normal up to 4th and then the converter will lock. Pulled 2 codes p0730 and p2703. Fluid is good, not burnt. Trans temp is about 150 to 160. I read the codes with my edge insight monitor. No tunes! Batteries and alternator crapped out on me yesterday. New batteries and a remain alternator that was tested. Bullet proof ficm tests good. Just trying to go camping for the weekend.....please help!

Re: p0730 and p2703 codes help!!

The first thing to do is to clear the codes, sort out the electrical system, and see if that fixes it. If the system voltage is low it can affect how the transmission shifts.

Re: p0730 and p2703 codes help!!

Thank you Mark. I already replaced the batteries and alternator and erased the codes. Also for good measure I pulled the negative cables for about an hour. The truck still flares the shift from (I have learned the proper shift sequence now) 3rd to 5th. Fluid is still pretty pink and smells like fresh atf. I'm thinking about replacing the direct clutch solenoid because it seems to be a common failure part.

Re: p0730 and p2703 codes help!!

Well something thatIi have noticed is that the trans shifts "normal" as long as the fluid is below 130 degrees. I have ordered a new direct clutch solenoid and am waiting for it to show up. Anybody else uave any similar issues? What did you have to do or replace to fix it? Anyone???

Re: p0730 and p2703 codes help!!

It could be the direct clutch solenoid, but that will usually set a P0766 with the 2703. You're direct clutches may be worn out. If you install the solenoid with no change, well, then the trans has to come out. Especially seeing that your problem is temperature related, then it is that much more likely that your direct clutches are worn out.

If you need to go through it shoot me a PM.

Re: p0730 and p2703 codes help!!

And the direct drive solenoid should not cause an incorrect gear ratio code, which is what the P0730 is.

Re: p0730 and p2703 codes help!!

Thats what I dont want to hear. I'm going to service the trans on my days off. I haven't done it in awhile. Hoping that will help. If its the trans then I will have to look for a rebuilt unit. Its possible that it is just worn out, truck has 225k on it and has towed almost its whole life. I have been trying a relearn sequence that I read about, works good for about 3 or 4 times then it starts shifting erratically again. Always the 3-5and 5-6 shifts.

Re: p0730 and p2703 codes help!!

Would not be surprised. Not bad mileage for a stock unit with heavy towing.

Sent you a PM.

Re: p0730 and p2703 codes help!!

So! Update time! The trans now shifts normal. No more flared 3-5 shifts! Not sure why..... The only thing that I can think of is that it finally"learned" after enough start and stops. Im wtill gonna service the damn thing. I did have one other constant code, cant remember the number but it was an internal keep alive memory code.
