LNF Gearbox lost 5th gear, need scheme, part list
 

Hi,
I lost on highway 5th gear. For sure lost oil doesn't know when, what was first. Gearbox will be taken out and checked what happend.
Need LNF gearbox scheme, part list but I found only for LSJ. If someone got it please post it. It will be really heplful for me.

Also searched for some used 100% working gearbox but found only case.

Greetings

Pretty sure LSJ and LNF gearbox's are the same. I know they are both F35 but don't know if there are any differences in final drive ratio. According to what I have seen F35 transmissions are not readily available but are out there for a price.

They used to be easily found and even new ones were plentiful but so many have been broke by high hp cars that they are in limited quantity now. Was thinking gm made a few more a few months back but I don't know who has them. You can still find used gearboxes for $500-1000. You just have to hunt. I believe 5th gear is serviceable with the trans in the car if there is nothing else wrong.

I have a full 5th gear set with under 40k miles on it I can sell you.

Founded used F35 gearbox with needed parts.
Now searching/order new seals, bearings.

Someone who service gearbox before me use too much hammer. This is why I lost 5th gear and oil.

Got simply problem can't find upper radiator mount bushing. These two upper rubbers on mounting plate and radiator.
