Question about 1992 Nissan 240SX Fastback
My trouble started almost overnight following some routine service (new plugs and brake service). The transmission use to shift smoothly, now it doesn't shift until the engine revs high. Could what you told -hedied4me7- that a vacuum hose from the intake manifold to the transmission modulator valve have something to do with it?
I have the same car too and i would check the fluid level on the tranny while on, located passenger side behind engine(yellow dipstick). Then as someone else had told you to check all vaccum lines. Check for tears of cuts or disconnected. Also maybe the torque converter is bad. I also feel like something internal may have gotten damaged from some unnessesary high reving. Not recommended for never serivced trannys but if you've been on top of ur fluid service get one now and see if that might help. Also is the original tranny and how many miles does it have on it. Age is always a factor.

The ignition switch is turned to the RUN or the START position.
When the ignition switch is in the RUN or the START position, the current flows from the B/U Lamp fuse located in the underhood bussed electrical center (UBEC) through CKT 839 (PNK) to the park/neutral position switch. The park/neutral position switch also feeds the backup lamps portion of the switch. With the transmission in the PARK position, the current flows to the BTSI fuse located in the underhood bussed electrical center (UBEC) through CKT 275 (LT GRN). The current then flows to the TCC/stoplamp switch through CKT 584 (LT GRN/BLK). The current continues to the BTSI solenoid through CKT 1135 (DK GRN/WHT). The ground path is provided through CKT 1850 (BLK) to G207. When the brake pedal is depressed, the normally closed contacts in the TCC/stoplamp switch open and the current flow is interrupted. When the current flow is interrupted, the BTSI solenoid de-energizes. The transmission may then shift to another gear. When the transmission shifts to another gear (except PARK), the contacts in the park/neutral position switch open. This condition stops the current flow to energize the solenoid when the brake pedal releases.
