Remove the positioning screws, washers, springs, steel balls, and reverse light switch. Remove the shift control mechanism and positioning pins. Remove the drain plug, fill plug, and vehicle speed sensor. Remove the transmission hanger. Loosen the transmission housing bolts in a crisscross pattern, removing them in three stages. Remove the sealing screws. Spread the retaining ring and position it on the secondary shaft bearing, then use snap ring pliers to remove it. Finally, pull out the transmission housing and positioning pins. Remove the reverse idler gear shaft, reverse idler gear, and reverse shift fork. Remove the reverse lock cam.

Hey, when it comes to replacing a transmission, I gotta say it's quite a technical job. I tried it myself once, and it was pretty involved. First, you must lift the car properly using proper jack stands—don’t rely solely on a jack, or it’s dangerous. Then, drain the transmission fluid, making sure the old oil doesn’t spill everywhere. Next, remove connected parts like the drive shaft and exhaust pipe. Loosen the mounting bolts and slowly remove the old transmission—it’s heavy and bulky, so watch out for hand injuries. When installing the new transmission, ensure the flywheel is perfectly aligned; even a slight misalignment won’t do. Then, reattach all the components and fill it with fresh fluid to the specified level. Finally, start the engine for a test drive and check if the gears shift smoothly. The whole process requires specialized tools like a torque wrench and takes at least four to five hours. I’d advise beginners not to take the risk—space is tight, and mistakes could damage the engine. It’s safest to take it to a repair shop. Regular transmission maintenance can extend its lifespan.
