Where is the transission on my car? - 1998 Cadillac Catera

Any codes,check fluid level,start car put in revers and turn off.Do a few times.

For an automatic there is a drain plug on the pan that you will take out to empty the system. Fill from under the hood where the dip stick is. Hope that helps you.

Could be a Clogged Exhaust Converter--if have no power
at all.

You need to replace the speedo sensor that bolts into your transission

p1715 = Manufacturer control transission

Is it due for a trans oil and filter change?

have transission filter and transmission fluid replaced

Removed trans? Take it to a trans shop. If you dont know what you are looking at, how do you think you are going to fix it? You should have checked line pressure first before taking trans out. trans shops need to diagnose before they take any trans out.

It could cause shifting problems, but it wont keep it from going in gear at all.

rebuilding the transmission will not correct an axle seal problem,thats a waste off money,have no idea where you got your previous seals but you need to get the seal at NAPA this time,and replace the left side cv shaft "This is the only thing that would ruin a seal" because of wear or burrs on the part that the seal rides on.And have another shop do the job,just in case the mechanic or who ever is putting them in,is ruining the seal by mis installation.

There isn't a drain plug. You just remove the bolts. Try and remove all but a couple from one end and you can pull it down to drain. Keep in mind that it will be stuck to the gasket. You can make quite a mess if you don't know what you're doing.
