2005 chevy van 2500 express is leaking tranmission fluid at pan

From empty to full it’s 9 course but all u need is 4 cours to top off the oil pan

check transmission fluid level also look and smell fluid if smell burnt and or color is brownish {color is a red } than change fluid and filter it may help but if metal present or heavy filings on pan magnet [and the problem persists } you have a problem that may need a shop to repair or replacement unit

Scan transmission module for any codes that may be present to point you in the right direction. These newer transmissions are electronically controlled throuigh various solenoids.

On most vehicles the transmission information is inbeded the VIN # or vehicle identifation number . Unfortinatly on GMC and CHEVY its not . It is stamped on the passangers side of the transmission at the rear of the oil pan just above the pan gasket you will likely have to clean it off to read it it will be a 9 digit # with letters being in it . The most common transmission for an automatic is the 4L60-E If the forth digit is D thats what it is . As far as the leak goes you need to deturman where its leaking from the pan gasket or the rear oil seal or is it comeing from in front . Transmission do not normanly leak so make sure that its not engine oil you are seeing that is being blowen back witch is much more comon . Transmission fluid is red and smells differant then engine oil and is thinner . Check the oil level on the transmission see if its red and dose it smell burnt if so it will be more black witch is vary bad . Do you have any shifting problems .Also check your engine oil to compare the 2 oils . In a nut shell its your vehicle and your the olny one that actully look at it and looking saves money and blindly replaceing parts costs a lot and rearly fixes the problem

Hi, you can download a manual here, but it does not specify the transmission capacity:
http://www.extendedgmwarranty.com/owners-manual/chevrolet/2006-Chevrolet-Express.pdfHere is the info you need:
4L60-E transmission Service change only - 5 quarts. Total refill - 11.2 quarts.

Total refill would include a tear-down of the transmission and empty the torque converter. If you are just dropping the pan and changing the filter, 5 quarts should do it.

Purchase trans fluid & filter kit from parts store. With vehicle parked and wheels chocked, undo trans pan slowly loosening bolts allowing one corner to allow fluid to drain (into a catch container of course). Pull pan once drained, remove old gasket, undo screws holding filter in place, replace with new filter, attach gasket to pan, retighten pan, refill.

u get a second look your self by looking at the transmission u dont have to take anything apart to find the leak the oil pan is easy so check that one first if u see any fluid on or around the pan then the seal is shot that dont mean the tranny will burn up, just keep an eye on the fluid level second the rear transmission seal is located at the back of the tranny where the rear drive shaft slips into the transmission if you notice fluid around there and on the drive shaft thats leaking also but like i said just because u have a few minor leaks dont mean the tranny will blow up just as long as you keep an eye on the fluid level. do your home work and find a good transmission shop that will gaureentee the there work at a decent price.

put a rubber tube over the dipstick pipe and siphon it out(it tastes orrible)

lOOK UNDER THE REAR OF THE VEHICLE ABOVE THE SPARE TIRE ON A CROSSMEMBER BETWEEN THE FRAME RAILS.
