what is a p1740

 

It's a code that has to do with tranny pressure in the 47RE if I remember right. Here's a TSB that covers some models for this code in case it helps. TSB 21-11-00

 

could this affect my mpg im avg 14.5 (so says the truck)

 

Well, never believe what that truck console tells ya for mileage. Never seen one yet that was right. But ya I'm sure it could affect mileage with that converter lockin and unlockin continuously. If it won't hold pressure it probably isn't stayin in high gear enough either. But let me be the first to admit that I'm a dummy when it comes to Automatic trannies so I'm sure there is some better info still to come here when other join in.

 

i c if i need a new one how much you think it'd run me?

 

1363.27 for a banks billet converter that would probably last pretty well...damn that makes me wanna look at getting a standard trans...

 

theres a reason i only have ever owend standards...........well a few actually!
