i have a few questions about my transmission ....How do i fill and check the trans fluid first of all i read other threads to where ya'll had said it was a big allen bolt on the right rear side i cant seem to find this i found 2 small allen bolts on the right rear but not one big one .....also where would i find a good place around oklahoma or anyone on here be able to rebuild or fix my trans if that is the case (which im sure it is ) thanks for your time

 

Maybe big is small in OK? The fill, drain plugs look like they have about a 25- 30 mm head.

 

passenger side, towards the rear of the pan, perpendicular to the ground

 

Ross, is there any dashboard warning messages that come if the ATF is low. I cant belive that a high tech XJ8 does not have a dipstick.

Is the refilling of ATF hit and miss, how do you know that the correct level has been refilled

 

There is no dipstick because it supposed to a "sealed for life" transmission which as we all know hogwash. There is a specific procedure to filling the transmission through the fill hole. You fill until the fluid starts flowing out while the fluid temperture is in specified range. You need to have scanner plugged into the OBDII port while filling the transmission. Also make sure you have the right Esso fluid designed for the ZF5HP24 transmission.
