I made the mistake of putting oil in my gearbox, only for it to pretty much all come back out.
Filled up to plug level on side
First look it’s coming from the front seal. I’d like to get the parts ready before pulling box out, anyone know the part number of the seal? Thanks
You sometimes get a drip but for it to be gushing out the seal must be completely shot or missing. When you take the box out again check the input shaft bearing for wear, I had a similar problem with an overdrive box and found the seal and bearing were shot - it must have been stored upright on the bell housing end for a long time in poor conditions so water had run through it and settled at the input shaft. Hopefully that won't be your issue.
