I can't make any suggestions on this one, ed. Mine is an automatic and uses ATF+4.

Do not use gear oil. It is too thick

"Shop Manual "TRANSMISSION FLUID"
Mopart ATF+4 (Automatic Transmission Fluid- Type 9602) is required in the 41TE automatic. ..."

"G288 and T350 Manual transaxles require the use
of Mopart ATF+4 (Automatic Transmission Fluid)
"

The early manual transaxle requires special MOPAR lubricant:

I was part of Team Shelby back in the day (mid to late 80's) . We used Mobil 1 5w-30 synthetic for the race car (G- body Daytona) trans with no issues. Will work just fine in a PT daily driver. My 02 manual trans I used Walmart Super Tech 5w-30 at 100,000 miles and actually shifts smoother now and cheaper. The extra I used in my John Deere engine 2000 13hp no issues.....

Thought the gearboxes needed ATF-4 because heavier oil made the syncro's wear out?
Is there no real difference in viscosity between the ATF and 5w-30?

OHHH YES THERE IS. ATF doesn't even list a weight because thats not what it is for.

ATF is basically a fluid with detergents in it. The whole point of ATF is to provide a liquid for pressure and detergents to clean stuff. Which in a Manual it doesn't even get used for pressure.

Engine Oil has multitudes of uses, Cooling, Lubrication, Multiweight features, ect.

They are not interchangeable. If they were, you would see a universal fluid you just put into one reservoir that powered everything.

Do not mix ATF with Engine Oil.

I wasn't going to - promise Just wondering why they say use ATF in the manual boxes - seems a bit counter-intuitive. But I read somewhere (cant remember where now ) that they use some kind of metal for the syncro's that acts badly with a heavier oil?
