Re: TH400 Whining...
Ok...ANOTHER update.
My truck has been sitting for the last 4 and a half months due to a BAD engine oil leak.
Two days ago, I got down to fixing the oil leak and went to pull the truck out from under my carport. There was some SERIOUS whining from the trans when I got it to fire up.
I tried shifting into gear, but there were no gears to be had.
At first, I thought that I had lost all the fluid from the trans, but further inspection told me that there was PLENTY of fluid in the pan.
Yesterday, after letting it idle for a minute or two, the whining started to go away, and I had gears again. I took it for a drive today around town and it's now driving just fine, albeit thought I do have a whine if I manually shift into first to take off.
Is it time to consider a swap or rebuild? Is this a case of the front pump going out?
I have a lead on a 350/700r4 from a late 80s van, and it makes sense to upgrade, but if I can keep this trans alive as long as I can, that would be awesome. (I've got a weird emotional attachment to it as it came out of my dad's 71 Monte Carlo )
Thanks guys.
