My trans has been acting up, the 1-2 shift is holding too long and then sometimes 2-3 does the same thing. the O/D light was flashing also. I changed the VSS sensor on top of the rear diff. and that helped out...some. What do these codes mean? What do I do now?

P0732
gear ratio error

P0781
1:2 shift error

P1670
No EF feedback -Not exactly sure what the original wording was since my friend wrote it down for me while I was working.

The trucks a 03 with 96000 miles on it, stock trans.

 

0732 Gear 2 ratio error
0781 1-2 shift malfunction
1670 EF feedback signal not detected.

The tests for the 1670 also reference a 1316 code (the dreaded UVCH one)

P0782, P0732, P0733 a SSA, SSB or Internal Transmission Components 2-3 shift error. Engine rpm drop not detected when 2-3 shift was commanded by PCM. Incorrect gear selection depending on failure mode and transmission range selector lever position. Refer to the Solenoid Operation Chart. Shift errors may also be due to other internal transmission concerns such as stuck valves or damaged friction material. May flash TCIL.

P0781, P0731 a SSA, SSB or Internal Transmission Components 1-2 shift error. Engine rpm drop not detected when 1-2 shift was commanded by PCM. Incorrect gear selection depending on failure mode and transmission range selector lever position. Refer to the Solenoid Operation Chart. Shift errors may also be due to other internal transmission concerns such as stuck valves or damaged friction material. May flash TCIL.

Unless you've got some damaged wiring or connectors, It's probably time to visit a tranny shop. It sounds like it might be internal.

The 1670 doesn't seem to fit what you describe. Do you have any issues other than the shifting? Maybe clear the codes and try to read them again after some more driving.

 

Thanks I was hopeing that it could be another sensor or somthing else, but it sounds like theres no other way....

Ill clear the codes and see if UVCH code goes away...if not well I have a extra set of pennie glow plugs that I might as well throw in there...

 

BTS anyone?

 

Thats what I would love to do, its still under warranty thought.....

Im goin to try to scrape up the funds for the BTS so I never have to worry about it.

 

You won't ever regret spending the extra money to get the best product that you can.
I have this attitude about spending more than average on whatever product I am currently in the process of buying.
I buy whatever is best to answer the need without regard for what it costs because I know in six months after the money is spent, I won't miss the money spent, but if I don't get the exact thing that I think is the best for the job, then I will regret the decision and wish that I had spent the extra money for the thing that I really wanted in the first place.
I've done the "wrong thing" more than once. The last go-round was over my injectors. I thought that getting a set of rebuilts would do the trick for clearing up some knocking noises that I was hearing that made me worry about an injector tip getting ready to break off. The set of rebuilts cured that problem, but the innard on several of them were in worst shape than the ones that I turned in as core and the truck ran worst than before, but sounded less harsh. Not acceptable in my book, but I had made the purchase and they worked so I really couldn't just send them back. They worked.
But for a year I had to put up with a fluttering miss at 5% throttle until I got fed up with it and bought a new set of Alliants and put them in.
That is what I should have done in the first place! Spend the extra $1000.00 on the new injectors and now the truck runs better than the day it came off the showroom floor. Eight brand new injectors getting fed plenty of air-free fuel due to the fuel pump mounted in the tank with no more mixing chamber or quick connects.

Anyway, I know that I am telling you how to spend your money, but consider what I have said. Brian makes one of the best trannies on the planet and backs it up with a great warrenty, and is reachable. (Meaning he calls you back real soon if he doesn't answer the phone right away.) That alone is worth a lot. And he and Jody Tipton know how to work with each other.

 

I agree with everything you said.

Since Im 18, alomst 19 and still live with my parents they dont think it would be the best way to go if its still under warranty...I have the money in my savings account for the BTS but they wont let me use that ...Im working on them since Ive been workin since Iwas 12 and the money is mostly mine that Ive worked for, other than what my grandma gave me before she passed.

I dont want anything other than a BTS in my truck, and Ill convice my parents soon enough.......hopfully lol

EDIT: Brians customer service is 1/2 the reason I want to go with him...you dont get that anymore.

 

I didn't realize you were that young. When I was your age there was no way I could afford a truck like that. I had to be satisifed with beaters or ride the bicycle. Raised by a single mom and the money was tight.

 

Yea I guess im one of the lucky ones, but Im not one of those kids that parents pay for everything...worked for every pennie that went into the truck, Thats why Im broke lol. I was brought up told that if my parents bought me everything then I wouldnt appreciate any of my stuff, and they were/are right.

 

While the BTS might be the best tranny around, if you have a warranty on the existing tranny I would look into letting the warranty take care of it. You're light years ahead of where most of us were at your age with a good savings account. I'd hold on to it and invest it in your future (school, house, future family etc.) No point in dumping all your savings into a truck you probably won't have 5 years from now.

 

I think this is great advice! It's easy to let priorities get mixed up once PMS has set in.....but in your case, college, or investing in trade school, or something to do with a CAREER is the proper thing to do (although it's not any fun!!!) We all talk about all the stuff we do to our trucks on here, but things like mortgages, food, clothing, bills of all kinds, etc....come FIRST! Get the warranty work done, that should be either free, or a small deductible. You can still save and get the BTS someday......Brian isn't going out of business anytime soon

 

The main reason I would go with the BTS trans is so I never have to worry about it again, and I plan on keepin the truck till it wont move and I am not capable of fixing it. In april/may Im moving into a house with 2 friends that my parents bought in fla but never use and takin over the payments on that house. Im not really goin to school at the moment just working in the family restaurant buisness managing one store and helping out with the other one. And I plan on doin this for a while. I basiclly support myself at the momnet with the excption of where I live. I kinda of alot of this figured out and with the amout of hrs I put in along with the side jobs I do I make good money. I could pay the small deductable but then I would end up haveing to fix it agian. Im with Dan and am a firm believer in doing things right the first time.

I understand what you guys were sayin though and thanks for the advice I understand why you would say all that and I dont want to come across in a bad way...

 

Don't worry about coming across in a bad way. You didn't. We were just trying to point out our experiences without trying to sound condescending because of your age. If your managing a restaurant, taking over house payments, and can still afford the BTS at your age, then you're doing better than most.

Have you figured out what caused your tranny problems to begin with? This would probably be good information to share with Brian.

 

The codes are as far as Ive gotten. Is there anything else I can do? If I opened it up myself and had a look I couldnt tell what nething was lol. I was lookin to see If I could get a mech. to look at it but I dont think he could tell me anymore then I already know, which would be that I need a new one.

 

I wasn't referring to what broke, more about why. I see the DP settings in your sig and I was assuming you occasionally have driving habits that match those bigger tunes may have had something to do with it. Make sure the guys over at BTS know exactly how much you want out of your truck so they can give you a tranny you'll be happy with.

From what I've heard theres a difference in having a chipped truck and having Jody's 140 aggressive tune. Nothing's indestructible if you try hard enough. I was thinking you might have been getting on it in 140 when you started to notice something different. If that's the case, that would be good info to share. As mentioned above, Jody & Brian are known to work well together.
