07 Yaris manual trans

[yaris9876]

I mistakenly bought Redline 75-90 GL5 for a trans oil. I have used the MTL 75-80 GL4 before. Will the 75-90 work? the Yaris has very high mileage but no problems with trans...

I mixed 1 qt of gl5 with 1 qt of the old used oil. good enough.

gl5 is a no no, ypu need gl4, gl5 will damage the transmission over time
