Nasty Burnt Fluids...Check Codes

Written By - Carman Clayber, Diagnostician

Recently a customer called to get a quote for a 1998 Ford F-150 4X4 with the 4.6L engine and 4R70W transmission. The price was given and we had one in stock. A couple of days later they called and told us they needed the transmission. It was still in stock, but late in the day so arrangements were made to get it delivered to them the next day. The technicians in our shops jump in and do whatever is necessary. This can be from diagnosing a complex electrical issue to dumping the trash, so first thing in the morning I loaded the transmission to deliver it. The shop was just finishing removing it from the truck. I greeted everyone and together we unloaded the transmission. I checked the core for components that need to be transferred like dowel pins and brackets. Everything had been removed so I loaded the core and headed back to the shop. When I got back the core was unloaded and placed on the drain bench. I did not know what was wrong with this unit as I had not taken the original call, however upon draining it YUCK, man did this fluid stink and boy was it black and look at the nice sparkles.
