Last week I helped my brother move home from university and while I was heading out there with a empty load, I had a heavy foot on those damn Canadian hills and shortly after that I started to smell gear oil or tranny fluid but there are no leaks any where. This was three weeks ago and I still smell it, Any help out there? also I pulled the dip stick for the tranny fluid and there was no foreign smell.
I`d rather push a Chev than drive a Ford

I would need a little more info to be shure but are you shure it's oil you smell burnin
Few questiopns to Try and Daignose the prob
1. What year is truck?
2. How many miles?
3. (Kinda obvious) do you live in the "rust belt"
4. Do you feel alot of heat by the doors of the truck when you get out after the truck has been running long enouph to get to operating temp?
5. Crawl under truck what kind of shape is the exhaust in ? rusty? new? does it have rust fall off if you grap the pipes and twist you hand around it?
If the answer to no. 3,4,5 is yes you more then likely have a pluged up Catelitic converter and or muffler
if that is the case you may want to replace the exhuast sytem
oh One more quetion you shure that oil you smell or is the smell more like rotten eggs useally the rotten egg smell is the first sighn of a bad Cat
Did you check along the TOP of the tranny and transfer case? If you can't see it leak it might have just blown through a vent line? Just a guess.
Someone mentioned O2 sensors and knocking catalytic converters. Wouldn't that smell more like rotten eggs than the beautiful smell of buring tranny / gear oil? [img]/wwwthreads_images/icons/smile.gif[/img]
