Synchromesh Fluid

[F4U-1A]

I did a search forums here, nothing came up. Having a very hard time sourcing trans not gender fluid for my 5sp. Dealership up here now ( no help, what's a manual C1500? go to the show room and buy new). I only have 350 ml of ACDelco #10953465, I had purchased many many moons ago. Is there an American after market OEM product I can find? Amazon, Rock Auto? The Black Flies are a biting now. All Good.

Maintaining a NV3500

I cannot find much info on the maintenance of the NV3500, no parts stores can tell me what fluid it needs, GM has the stuff but it's $30/litre I'll need two My truck is a 1995 Chevy Cheyenne 1500 4x4 with the NV3500 5 speed Couple questions would be: Is there an alternative to the GM...

Thanks, I was about to try Napa in town here.

Update, they have two quarts left in town at Napa of Pennzoil on hold for me. I believe the Synchromesh is for smoother shifting in the winter up here. But I park the Chevy when the snow flies.

As a general rule, GL4 for gearboxes, GL5 for final drives. The anti-wear additives in GL5 attack yellow metal synchromesh parts.

Run Amsoil signature series ATF, way better then the AC Delco or any of the others. You will never regret it.

If it calls for synchromesh, put that in there! Do not put gear oil in it, it'll shift like garbage any time the weather is under 60F. As 1997 posted, the Pennzoil stuff is a good alternative to the GM stuff. I put A/C Delco in my 1989 and put Pennzoil in the 1992 as I couldn't get the GM stuff. I haven't noticed a difference with either truck other than shift quality improved from the fresh stuff. My trans had gear oil in it before. Both trucks have the same transmission, the 5LM60.

Amsoil makes a synchromesh fluid also. It’s supposed to be really good also. Not sure what it costs. Probably expensive

The task that was at hand, has been completed with Pennzoil. Thank you for all the input.
