Impressive..professionals can diagnose from a far. Thank you
When I read: "typical of gearboxes that have been without oil" I swallowed three times, took a moment away from the reading...
Indeed, there was a heavy leak. I replaced the 93 gearbox with an older 88 model. The 93 gear box has the side cover with the(cant check oil level) nut. In the haste, I mounted the older(with hole and dipstick) box, yet did not switch covers. I cant recall precisely if the 93 box was easy to get to, or I told myself i eould switch later on the car.
As this vehicle is an S model, it has the exhaust pipe tgat runs close to the cover, so one must drop the exhaust to access it. That contributed to laziness. What I did was cork the hole/jambed it..but seeping of oil was evident a few days later. I fell into "plumbers have leaky pipe" trap.
A while later; a pool of oil notice- that cork was gone! Gaping hole; long story short..whining began after going into 3rd gear. I poured oil; quieted down..then reappeared. Oil made no difference in terms of the whining in 3rd, now 4th. I, the careless one; kept motoring along..with the intention to "fix in a few weeks. I have rebuilt quite a few gearboxes many years ago...but I realized especially after reading your reply...that I was simply a parts changer..not a person who could diagnose- as you did through the computer. There lies the difference.
Questions, if I am welcome to bother you some more:
Is the whining from the box usually the pinion bearings? If it whines in specific gears(in this case...3rd and forth) does the point to the gears themselves?
Being that it was driven less oil; should I expect the pinion gear to be unacceptable? I'm also wondering if the forks,etc
I'm wondering are parts still available; such as that layshaft that always needed to be replaced for that wirn area under the bearing.
That tightening of the pinion nut/crush spacer preload set up:
Do you follow the manual with the instructions to use the spring tool with the hook? I did buy one years ago, but was told by a Saab tranny rebuilder, to just tighten the nut as hard as I can...where turning the bearing housing took a bit of medium force to turn.
Also, should the metal gasket between the trans/engine be replaced with grey silicone-skipping the gasket completely?
Thank you in advance Cmyles..great help. Appreciate it.
