Toyota Celica 5-speed manual transmission issue with popping out of gear and failure to engage on Toyota Celica

Some Toyota Celica owners report experiencing issues with their 5-speed manual transmission, such as popping out of gear or failing to engage. Common symptoms include difficulty shifting gears, gears slipping, and unusual noises. One potential cause for these problems is worn synchro rings, which are essential for smooth gear shifting and can lead to the transmission unexpectedly disengaging, particularly in fifth gear. Additionally, issues may arise from worn mounts, loose linkage, bad shifter bearings, or a weak spring in the shift rail. In some instances, internal transmission problems may require a rebuild or replacement. To resolve the popping out of gear issue, some owners have found success by adjusting the spacing with different thickness snap rings for the transmission shafts or replacing the 5th/6th shift fork. It is advisable for owners experiencing these issues to seek professional assistance for accurate diagnosis and resolution to ensure the proper functioning of their transmission.
