Thread: 68RFE Trans Codes: P0933/P0935?

    68RFE Trans Codes: P0933/P0935?

    My buddy's truck lost weight this weekend, plus we added a Revmax VB and CCS tunes.

    We did a proper relearn, and codes P0933 and P0935 are coming up.

    Reseated the sensor on the side of the trans and deleted codes to no help.

    He is getting a new one from the dealer tomorrow, so that we will see.

    CCS is using Revmax specs which I've used before, and mine was ok.

    We have some trans guts from the same mechanic, so it has to be a faulty valve body or that sensor.

    UPDATE.

    It was the Revmax valve body causing the codes and issues.

    New stock trans tunes didn't resolve; the new sensor didn't fix.

    We put the stock vb in yesterday and did relearn, and now 300 miles and no codes.

    My buddy is going to see what Revmax will do.

    So we will see if Revmax has good service because this defective vb cost him and me alot of labor and money.

    I subbed to hear how Revmax handled this, and I'm sure they would want the VB returned for inspection first

    They tested it, and it passed.

    They offered to send my buddy another VB with a solenoid pack, but he is undecided as he uses it for his Bobcat work, and business is booming.

    He doesn't have the time to mess with it.

    Very odd that the stock VB works with no issues.

    Very weird you swapped the solenoid pack on a new VB or ordered a new one initially.

    It is nice they appreciated sending another one, but it doesn't help your buddy as he's out the labor and the cost of the Revmax VB.

    It was my time/labor until the 3rd time I made him do it while I supervised, LOL.

    He is a pro now.

    He said Revmax did send him a new VB and solenoid pack to try yesterday, so it looks like he will be dropping pan again soon.

    I had no issues with my installation, so it is weird.

    He probably can do it in an hour now after the third time, LOL.

    At least you know the gasket surface is squeaky clean of old RTV (I assume he's not using a stock pan with RTV each time?)

    Please let us know if the new VB from Revmax does the trick (did he get the Billet or Tow/Street version?), and either way, for the investment cost, I'd want to hear that he is liking the benefits of the Revmax VB.

    Did those codes cause his converter to cycle in 6th gear?

    I have the same codes; I installed a babymaker valve body roughly 20k miles ago.

    I am wondering if this isn’t my issue as well.
