You have a wonderful day. Best wishes. Deas Plant.
Hi, Au7edd.
There is a dipstick for the tranny, either under a floor plate or under the seat - it's been a LONNNNGGGG time since I was around one. If at all possible, check the tranny and the engine before running, then run the machine and at least drive it back and forth a bit, then check both again to see if there is any color change in the oil.
The 977Ls are a pretty robust machine.
Just my 0.02.
