TH 350 - shift up and down 2-3 permanently Hi,
I have an Impala 350 cui with a TH 350.
Since a couple of days the tranny shifts up and down two times a second. I have the feeling that this is mostly the case when the engine is hot aftewr 10 miles.
I have changed the oil and the filter, and the oil level is correct.
What yould be the reason for my problem, what can I check?
James

CHECK THE vacume line to the modulator check that its hooked up. Not collapsing and that theres no trans fluid in it.

No fluid type would have no affect, Do you have the PASSING GEAR "DETENT" cable hooked up maybe its to tight

I removed the detend cable and I still had the problem. I think a TH 350 do not need a detend cable, because it is only necessary for downshift. Is this correct, so can I do something wrong by adjusting the detent cable?
No the tv cable being unhooked would eliminate its as a possible cause, I have not run into what you have going on , Very strange
