When I loaded the tunes I ran the performance tune and my transmission began to shift funny and the OD lght on the shifter began to blink What would cause this thanks

 

03strokinfl, are you running our tunes? You said "performance", is this the SCT base file?

 

Also what engine model, year, and mods if any to your truck. 6.0 equipped trucks do not have a OD light or button on the shifter. They do have a tow/haul button on the shifter.

 

From another post of his:

 

Ok, just maybe using the wrong terminology. Was thinking he had a 7.3 truck, from his initial description.

 

It is a 03 f=250 6.0 diesel the only other mod I have is exhaust the tunes are from LI diesel

 

How much does Spartan diesel charge for tunes

 

03strokinfl,

Give us a call tomorrow, I will discuss some pricing options with you on our tunes

Matt @ Spartan

 

If the tunes are out of calibration badly enough to trigger a flashing Tow/Haul light, there are some serious issues at hand. Flashing Tow/Haul indicates an "incorrect gear ratio" DTC or malfunctioning/out of calibration solenoid in the transmission control module, which is indicative of severe transmission slippage between one or more gears during up or downshift.

You would probably be best advised to remove the tuner and send the truck in for transmission diagnosis, and at the very least a fluid change. If everything checks out OK, let us know, and we can discuss some tuning options.

 

I think I see the root cause of your problem.... it's LIPD related.... RUN don't walk to a phone and call Matt..... whatever he charges you for tunes will be less than the damage your causing to your truck right now.....

Apparently Jeremy has tried his hand at programming....

As I've said before.... any idiot can buy the software only a few experts know how to use it......

 

There you go being politically correct again.

 

Wow this only took a week of running LI tunes.

It definitely sounds like you have some definite transmission issues. Return truck to stock tune and troubleshoot your transmission problems. Then talk to Matt about some custom tunes.

 

You can also try DJ's Performance. Truck shifts perfect, just a little firmer than stock.
