Hey everybody i have a rpm question. Now usually when im cruising at 70 mph my tach reads 2000 rpm. Now while im driving at 70 mph it is reading closer to 2500 rpm. Im not sure if this is related to the issue but this past week i attempted to use one of the ac fix cans to no avail please help mildly concered i screwed something up

 

Not related to the AC. Most likely a problem with the TCC, (Torque Converter Clutch) solenoid in the transmission. Is the SES, (Service Engine Soon) light on? If so, have the DTC's, (Diagnostic Trouble Codes) retrieved and post them here.

 

Ok well if it is that; that's a relief the trans is under warranty. However no ses light ill keep an eye on it and let you know if i get one thankyou for your help

 

if abs system is defective/or fuse is blown, the tcc will not lock.

 

The abs is fine in all honesty if I didn't know that the truck was usually at that rpm you wouldn't know anything was amiss with the truck no dash lights are on and the truck is still hauling ***
