Hi,

Is it ok to use Motul Gear 300 75w90 GL-4/5 in ap1 transmission? I read a lot about tranny fluid for ap1 on this forum and i found out that the oil needs to be API GL-4 and this one is.

Has anyone tried this oil in transmission?

sory for my english

Thank you for your answers

 

That fluid is a bit too viscous for the transmission. Why not Oem fluid, it's relatively cheap.

 

oem fluid is more expensive here, and in hot summer sometimes it feels to thin. I would like to try it if it will make shifts smoother , sometimes (very rarely) i do get a little grind from first to second gear .

I just want to know is it safe to use in ap1 tranny because it says both APIGL-4 and 5. people at Motul are recomending it now for ap1 also cause they have changed the formula to suit GL-4 trannys also.

 

Shouldn't be any problems using that. It's not a big difference in viscosity, I think the oem fluid is 75W-80.
If you are tracking your car it might even be better.

 

yes im planing to track my S this year once a month ,
i found this technical data form motul´s site and it says: Suitable for any type of seal and yellow material used in gearboxes design.
Anti-corrosion, Anti-foam...... soo yaaaay i just ordered 2 litres of Motul gear 300 for tranny and Motul Gear 300LS for diff.... cant wait

Thanks for your help

New vtec solenoid top gasket thanks to Balladesports .

I am amazed with Gear300 in tranny.......smooth shifts (probably needs a few minutes of driving to warm up, but its smooth even when cold), 2nd gear grind dissapeared, 3rd gear notchyness dissapeared, less tranny noise......... il se how it does in summer when its very hot . Honda MTF was terrible in hot summer.

 

I replaced the honda fluid with Amsoil trans fluid. There's really an improvement in shifting now.
