What is this solenoid thing with 4 wires on it? What does it do?

 

Reverse/5th gear switch

 

You beat me to it. I just found it in the FSM, though it didnt look the same. What exactly does 5th matter? What does it do when your in 5th?

 

damn...youre really getting the rebuild goin pretty fast...what all have you done so far??

 

When you're in 5th in keeps the shift lifht from going off.

FCKing you are my buddy.

 

Not really a rebuild. Just clutch and flywheel install, along with all new external gaskets and seals. New trans front cover and seal, clutch fork and pivot. front and rear main seals, all new gaskets on lines and whatnot. all emissions blocked and some other junk. wastegate ported. most engine parts cleaned and painted... I have a thread on it somewhere on the first page

 

ahh, well good, it doesnt matter that one of the wires got broken. None of my lights work properly anyway lol.

 

Fifth, or over the top switch, is used to trigger open the Split Air Solenoid on the ACV when you go to fifth gear. It does that by putting a ground on a pin of the ECU which in turn puts a gnd on the solenoid. That's for a non turbo car.

On a turbo car it puts the gnd on the Split Air Solenoid directly without going thru the ECU.

 

ahh, thanks for the help. im still safe as my acv is gone. split air... ha
