Only makes spinning sound after being put into gear

[vet67coupe]

Hello went through some high water this evening maybe 8 to 10 inches 1989 toyota 4 cylinder running fine. Wife said seem like it started to jerk toward passenger side. After driving through water drove about 2 miles turned started back now after starting makes a winding spinning noise and strong growl noise when putting into drive doesn't stop till you put it back in park......any help would be appreciated in the dark on this one....Also went out the next morning car pulled back and forth and then did the same thing loud spinning noise that didn't stop till put back in park.....BiLLL

if noise is supected to be from transmission, the only unit that spins when car is not moving but in gear is the torque converter.
If noise is present when car is moving, is related to the drive train [gear sets, differential, or bearings]
If transmission is ECT type look for my thread about "torque converter noise forced lock-up test".
Although it possible that water can get into tanny [which will turn the fluid into the "pink yougurt" color], the front pump is most likely to suffer from that [which will make RPM related whine].If fluid is pink, the clutches may also be damaged by water /ATF mix.
You may need to drop the pan and inspect.
Good luck
