Thank you for the input. I can’t believe it takes so long to get “goop” but glad you told me not to use synchromeshYou sir have an NV4500. use only the recommended fluids NOT SYNCHROMESH! The wrong gear lube will murder your synchros in short order. I have been waiting on my rebuild kit for mine for a year!
The original fluid Was Castrol Syntorq which is long gone. GM has a safe gear lube as Dodge. You can get it at the dealers.
My AC Delco fluid has been on back order for almost a year. Do not use GL5 gear lube as is etches yellow metals (brass) synchros. The synchros have carbon fiber linings which is why you need to only use the right goop.
Redline says their MT85 is safe as well. Some sources recommend overfilling the 4 quarts. There are coolers and filters available that can add capacity and drop temperatures that take the place of your PTO cover plates.
O.K. rant over.
The drain plug is the bottom bolt of the PTO plate. Standard fluid capacity is 4 quarts.
