i replaced my clutch in my 88 yota today and changed the gear lube also, i put 80w90 in it just to get it out of the shop... now it takes tremendous force to down shift, would that be because of the gear oil or did i screw somethin up? i no it takes 75w90 but all i had with me is 80w90... i did research on this but nothing gave me a clear answer

Trannies can be quite picky about what oil they use. Sounds like you used an oil which is too slippery for use in a manual transmission and the syncros aren't working properly. I suggest you go with Redline MT90. Its about $40 in oil to fill the tranny, but it works beautifully, don't know about any other types of fluid.

thanks for the info... i was scared ha ha

Make sure you are using GL-4 in your tranny, GL-5 can damage the Syncros. I use AMSOIL Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 API GL-4 (MTG), and it has made a huge improvement in shifting smoothness.

where can i find those kinds of oil i am looking at servicenig my 5 speed soon and would like to use something like that either one but i guess gl-4 is what i am supose to use? 1984 straight axle. 4cyl

Yes, should work for an '84. Those are W?? trannies right?

yes i would also like to know where to get the red line stuff

Elton

i ordered red line from summit racing

I bought mine from Lordco- a local BC auto parts store.

would it work in my transfer case?

AND...it'll probably last 2x as long as non-synth gear oil. OK in transfer also, but do not use in differentials...GL-5 for the diffs.
