well i did do that rite all three are 13ohm any other item to check thank you very much for all the help

 

VSS? I say that because my lockup doesn't occur until 45mph, and the VSS does send signals to the TCU. Otherwise, have you swapped the TCU?

 

VSS this is the safety switch with the black 8 pin connecter.is it just easy to go buy one or how can i check. I am getting another TCU from a freind that i know works

 

VSS is the vehicle speed sensor on the tailshaft of the trans, driver's side.

If you're getting a TCU, try that first. The VSS isn't expensive and is easy to replace if you get one with the OEM type connector. Napa sells a replacement that requires cutting the old connector off and spicing a new one on.

 

ok changed TCU still same is there a way to check VSS or shall i just buy one thank you again for all your help
