200 4r Tcc Solenoid Wiring Tips Youtube As we wrap up the transmission rebuild we need to finish installing the electrical lockup components. in this video we install all of the electrical componen. 2807 posts · joined 2011. #15 · may 5, 2011. you must have a 6cyl to be running a 250c. that model is actually pretty rare compared to 350's, 200's, 200 4r's etc,etc. it lowers the rpm's by about 250rpm's. you can set up a lock up system for it if you really want to. some guys run an on off switch on the dash.
200 4r Wiring Diagram The wiring for the th350c & the th200 4r is different in that the tcc solenoid in the 200 is earthed through the transmission case & in the 350 it's earthed via a relay controlled by the ecu. on the 350 case connector pin a is 12v supply & pin d is the return that the ecu earths. Use a normally open pressure switch installed in the 4th gear pressure port of the valve body,700r4 0r 2004r.wire the terminal to solenoid ground.supply 12 volts key on to a th400 single wire case connector installed in the case in place of the 4 terminal oem type.wire the inside of the case connector to solenoid positive.if the engine lugs. Unbolt the tcc solenoid near the front of the case, it will have 2 wires going to it. remove the governor cover from the rear pan area. (4) 13mm bolts. remove the governor. remove the wiring, 1 2 accumulator housing, parking pawl bracket, transfer tube, and valve body bolts. There are too many variations of how the tcc is hooked up, between various 200 4rs. i would advise pulling the pan and confirming which pins go the 3rd and 4th gear switches and which two go to the the solenoid. here are the variations between the 200 4r for the vin y application and the 200 4r for the vin 7 buick applications:.

A gn has two pressure switches, one for 3rd, another for 4th. most other generic 200 4r's only had a 4th pressure switch. then from year to year the wiring changed. so the wiring is not the same, nor universal, unless you start from scratch. a normally open pressure closed switch is available from gm for ~$24.
