Tranny issue
Well I think I know what the problem is but Ill get some of you guys output. So my tranny is whinning loudly 1st & 2nd gear and little in 3rd. 1st and 2nd sounds like I have a supercharger basically. It didnt start doing it till after I swapped the engine. I put full synthedic 75-90w gear oil in it. It seems to shift fine and be normal but makes the whinning sound which drives me crazy. Im just hoping it isnt gonna take a dump on me. Im gonna drain all the gear oil out in a couple days and check the drain plug to see if it has metal shavings on it. Ill also use a screen on everything that drains out. Hopefully I dont find nothing. If I do....Looks like Im gonna need another tranny. Advance in my area doesnt carry redline so what do you guys recommend me to run?
