What gearbox oil should i try now?

have Redline mt90 in the car now dosent like the notchy feeling when the car is cold and that is hard to put in gears when the car is cold.


Should i go to Motul 300? think that i seen somewhere in here that someone wrote that motul also was notchy when the gearbox is cold.


Which oil should i choose if i want smooth gearchanges and easy to put in gears when the car is cold.


Car: Evo 4 GSR

 

Pennzoil Synchromesh or BG synchroshift. Just be sure to change them more frequently as they will degrade faster than the stock tranny fluids. Recommend changing Pennzoil Synchromesh every 9000 miles and BG synchroshift every 12000 miles.

 

Motul from day 1 in the drivetrain and no problems, no unusual wear - except for my wallet I guess. Plenty of track days, many runs exceeding the typical 20/25 mins. Later this season I'll install a temp gauge and have more to offer than conjecture and commentary on the fact my magnetic bolts are pretty much clean on drains.

 

transfer case: redline heavy weight shockproof
transmission: bg syncroshift
rear diff: redline 75w90 with friction modifier
