Brad :

Hello and welcome to JustAnswer, My name is XXXXX XXXXX I will be assisting you... The P-0700 is telling you that you have a code in the TCM.. The P-0733 is Gear Ratio Error in 3rd.. How does fluid look?

Customer:

due a filter change, but looks okay not burned

Customer:

I hit accept button in error please continue

Brad :

I don't see where you hit accept... It's fine.. Will it shift into all the other gears fine?

Brad :

Is your speedometer working?

Customer:

yes

Brad :

Click HERE to download the diagnostics for P-0733..

Customer:

done

Brad :

You said that it rev's up when it shifts into OD... Is that the only gear it does that in?

Customer:

no when it attain speed it feels asif it drops the gear and freewheels

Customer:

then it over revs and slams into gear

Customer:

finally

Brad :

I understand... You may have faulty seals, and when it rev's up the pressure gets high enough to slam it into gear...

If you run the diagnostic check for the code P-0733, that will lead you to the faulty part or parts and then you can repair your vehicle...

Brad :

Have I answered all of your questions?

Customer:

finally seems to go into limp mode perhaps second gear

Brad :

Yes, anytime the transmission sees a fault, it will go into limp mode which is 2nd gear

Brad :

if you shut it off, and restart it it will shift again until the fault appears again

Customer:

problems not related to 0700 code and TCM

Brad :

The P0700 is just a code to tell you that you have codes in your TCM

Brad :

Have I answered all of your questions?

Brad :

If you need anything else, feel free to ask

Thanks,
Brad
