THM 400 transmission not shifting
THM 400 transmission not shifting
why is my GM THM 400 is not shifting first gear ontime? it will shift after the enging starts to rev-up. all other gears seam to be working fine.
Re: THM 400 trasmission
Could be a vacuum problem to the modulator.
Check that its vacuum hose is good.
Also may need an adjustment.
There is a phillips screw insde the vacuum port on the modulator.
