Baystate Jeepers

2000 TJ, 5 speed stick. ~160k and doing a fluid change on the gear box and my question is, am I better off going with the factory recommended lube (75w-90) or should I listen to the YouTube experts and go with 75w-140?

I’d stick with the 75w-90

Redline MTL if NV3550
Redline MT90 if AX15
If you use something else make sure its gl4 or a yellow metal friendly gl5

Thanks guys
