W56 4WD tranny problems

I have a 1989 4 Runner 2.4L 4WD PickupQuestion:  I have noise coming from the transmission on all gears except the 4th gear. I had the noise before, then I replaced the clutch disc, pressure plate, release bearing and pilot bearing.The noise just got worse. 4th gear is still quiet/ Driving at 65MPH, the 5th gear has a high pitch whining sound. Do I need to overhaul my transmission and would I need all the parts including synchro and input shaft? Is it a W564X4 tranny?Answer:  This is usually a result of running low on fluid damaging the input and cluster gear.  We recommend the following parts.
