whining noise
I just put in a 338stroker, it makes a whining noise that gets louder when Im coasting and slowly goes away as I accelarate, Im wondering if the converter is to tight and I need a higher stall, Its got a th350 with stock stall
Hei, long tube headers, ededl eps intake, 1406 carb, any thoughts, thank you, |

Re: whining noise
Your description of the whining makes me think rear axle ring & pinion, noisy coast and quieter under load. Also maybe a planetary gearset in the trans??
I'd have to hear it to really say. Does it change with RPM or MPH? Is it present in all 3 speeds?

Re: whining noise
ya it does change with rpm, just put new gears in but it did it before the new gears, it sound like its right under the floorboard,

Re: whining noise
Maybe your inspection cover on the transmission might be rubbing on the flex plate?

Re: whining noise
Is it at the rear of the truck or at front? Could be Alternator ?

Re: whining noise
I thought I had the same problem,but the whining stopped and now she`s in Florida...
I`d think you`d definitely want a higher stall.I`ve heard what you describe and think it is in the converter.
