Our smart tech said gl-4 or gl-5, doesn't matter, as long as it's the proper weight. Although he was confused at the reason to even change it since it's 'supposed' to be for the life of the vehicle. I wasn't about to keep those filings in there...

smartUSA approves the same Castrol BOT 328 75W-90 GL-4 that M-B does (only), but also Mobil Delvac Synthetic Gear Oil 75W-90 and Mobil 1 Synthetic Gear Lube LS 75W-90, again "only" (not surprising in R.P./smartUSA-dom). Both Mobil products are GL-5.

Herein is the glitch: ExxonMobil does not recommend the GL-5 Delvac be used where the specification is GL-4, and they only allow the GL-5 M1 LS be used in AXLES, with nothing said about TRANSMISSIONS. My smart center uses the M1 LS. I'm a bit concerned because scVAB used the M1 LS at my 5,000 mile transoil flush.

Pennzoil does make a true synthetic, GL-4, 75W-90, and with a different specification than their GL-5, 75W-90. The trick now is to source their GL-4. Others are available from Amsoil and Redline.

M-B continues to cleave to Castrol BOT 328, GL-4; I'd like to know GETRAG's independant take on it.

I had the same thought after I posted. Maybe an inquiry to GETRAG is in order...

How do you separate the engine from the transmission??? Does the flexplate need to be unbolted from the flywheel? What about reassembly?

Thanks,

I don't think you will find a flexplate, just a flywheel and clutch. It is not an automatic transmission and that is where you would find a flexplate.

Actually, back in the day, OLD SMART did contact Getrag and THEY answered back that ONLY Castrol BOT 328 was tested and approved

I searched around and found that GL-4 was the proper lube, seems GL-5 contains something to harm the transmission, I changed mine at 30,000 and again at 60,000, both times fluid was dirty, silver looking and tiny particles. Anything with meshing gears will wear, keeping fluid changed can help it last longer.....
