i have been noticing some howling type noise in my truck. i think i have isolated it to my transmission. the sound is the worse in reverse. especially when you first shift into it. while on blocks i couldn't make it happen in forward, but while driving down the road (55mph or so) i can make it out.
the tranny itself shifts good up and down has had a recent fluid change. no real delays when going into gear. it dosen't seem as tight when it is cold little more sluggish. could be the fact the whole truck is cold (axles, transfer, motor, ect) anyways im hoping my tranny isn't about to explode. any thoughts???

 

i did find this article in my searching

Did U Have The Trans Flushed When U Had The Fluid Changed? I Heard Alot About How It Can Dis Lodge Pieces Of Crud And Clog Some Of The Valve Body Ports. Just A Thought

 

any thoughts?? im thinking about putting a tranny gauge in to watch temps. what is normal temp readings?

 

anyone? kind of nervous where can i read about this tranny? i have searched the heck out of this site

 

I think it's the rear.

 

interesting thought. what makes you say that? i just bought gear oil. im planning on changing that soon.

 

wanna has a good point. Rears howl when they start to go, especially at higher speeds. Before you go too far I'd say pull that diff cover and see what it looks like. Check for metal shavings, etc. Its also not a bad idea to pull the carrier bearing caps off to check the bearings. Dana 70s are known to eat them up, especially the one on the ring gear side. I dont know a lot about the autos, but I'd say check out the rear first.

 

thanks guys, im going to pull the cover off tonight.
