Hey guys where do you buy your transmission oil? Not the hydraulic oil.
I think I put the wrong oil in my 4C (redline mt-85 gl4)

Its changing gears rough now and threw a gearbox warning on the dash where it wouldn't let me put it in gear. I unplugged the battery and now it works. But I suspect these issues is with the oil


Every link I find with the compliant oil MS.90021 or 9.55550–MZ3 is no longer for sale.

Although I’m a fan of Motul oils, I would be reluctant to use the Motul MF Fluid in the TCT system (even though it says it is a substitute for Tutela CS Speed) as it doesn’t have a classified viscosity…

You can get both from any dodge dealer.

The dodge hornet and AR tonale uses the same trans.
Wtf? 😂 The only things common with these transmissions are them both transferring the rotational energy from engine to the wheels and both identifying as "trans" in general.


@AlfaNY Harri what do you use in 'murica?

I use the OEM Mopar fluid. The one that says it's designed for Alfa Romeo 4C and Dodge Sprint shift (a.k.a shitshift) transmissions on the back label. That gear oil is actually red... Just a cool fact.But in general the 70w85 from Tutela, redline and Motul are all good.



You have to measure the fluid when filling up the transmission. There isn't way to check the fluid level correctly.
