After replacing the shift cable bushing on 2003Toyota corolla. My automatic transmission will not move forward or backward.

Who is Jose Nixon?.......Extreem backlash in CV joints..

Hey Jose,
Have you made sure you have the transmission is full of fluid..check it with the engine running ...USE ONLY transmission fluid! ...You did not mention the make/model and mileage. It might be time for a transmission overhaul....see a qualified professional..

the gear selector cable has broken

Sounds like the shift cable is off the transmission under the hood. Raise the hood and check to see if the cable is moving the linkage going into the transmission when the shift lever is moved in the car. Be sure to have park brake on.

On some European cars there is just one shaft from the gear shift leaver that operates the transmission. First make sure all the bushings are good unlike American cars European cars are not forgiving for loose or worn bushings. On the cars with cables there are two cables on for going forward and backward one for going side to side; not the gear position how they move the Mechanisms Make sure the bushings are not loose or worn and check cables for breakage. Make sure to check under the rubber boot usually by removing the center cover between the two seats if the cable or mechanism has broken it usually near the shift inside the car. Usually the pressure for going side to side is equivalent for going back to back there should also be a click feeling as you move the rods in the transmission by moving the stick both sideways and front to back. If it is not the cables or the outside mechanisms it usually is one of keys usually a screw in the detent mechanism in the transmission which means the transmission has to come out. Unfortunately they stopped making that serviceable in the 1970's. A 1950's Chevy for example has that mechanism on the side of the transmission instead of on top.

check the trans shift linkage at the transmission. the bushing gets old and pops off the range selector switch.

replace your transmission pan filter it is clogged; no fluid movement no forward or, backward movement of your vehicle.

check transmission fluid first.if its low add to get correct level.if transmission fluid look dark smells burnt replace fluid and filter.if car still dont move forward.looks like you have bad worn out forward clutch plates and seals.also bad transmission oil pump.you need a overhaul or new transmission.

What you can try is to remove the shift cables from the transmission side. then move the shifter and see if everything is free if it's still sticks then the cables are going to be replaced. if everything is moving with the cable off. then you need to remove the shift tower on the tranny (where the shift cable is I belive it's 5 bolts) remove the tower and you will see the shift pin. Inside the tower there is a cotter pin that breaks and that will cause you to have one gear and unable to selected another gear. If you are not mech inclined I would no attemped the shift tower repaire, the cables do it will save you money. The shift tower has bushings that can fall into the tranny.

it sounds like something broke inside the transmission
