Without fluid an automatic transmission will never work. Just hope that you haven't destroyed the clutches by attempting to run the transmission with low fluid levels. The drive shaft should pull out of the transmission after removing the 4 bolts from the differential. you should be able to see the rear seal after the drive-shaft is removed. Most REAR seals can be pried out and carefully replaced without too much difficulty or experience, but be careful to not bend, nick or otherwise damage the new seal as you press it into position. You may need to tap the new seal with a hammer and some kind of device that puts pressure on the entire seal to press it in evenly. If it works, (doesn't leak and the clutches still function) you're in luck, but I'd change the fluid and filter as soon as possible. If it doesn't work, you get to buy a new truck or a new transmission.
The seal should run about 10 dollars or less. The mechanic shouldn't charge more than 40 dollars or so. It is a pretty easy job. Buy the seal, remove the driveshaft, knock the seal out, replace it with the new one and reinstall the driveshaft. Piece of cake. good luck.
I was not aware that headgaskets were repairable. I have always replaced them with new gaskets. If you mean who replaces headgaskets, then that would be an engine mechanic.
A qualified mechanic
Yes, and mechanic can change your fluid.
Probably a bad driveshaft. Have it inspected at by a mechanic. Sounds like you need to check your CV joints. To my knowledge a front wheel drive vehicle does not have a driveshaft.
The mechanic told me the the auto's transmission had been overworked.
Any mechanic that will listen.
take it to a mechanic n have them do it
