I just purchased my second old school Corona Mark II this one has a few engine problems but seem to be a pretty solid car other than that. The Chassis Code is MX20 and it is labeled as a Corona Mark II L. It has either a 2M or a 4M engine inline six cylinder. The engine problems are pretty simple fixes but it has an automatic 3 Speed transmission that when placed in reverse will not engage. When the car is placed into reverse there is no movement. There are no strange noises or anything coming from the transmission. All the other gears seem to be ok. I believe the transmission code is A30 but that is just from online research. I am looking for any information on the transmission and what can be done to fix the reverse problem or what transmissions are compatible swaps for the car. If anyone know what parts will be needed to fix the problem or where a good source for old transmissions are I would greatly appreciate any help. Please keep in mind I am located in Tokyo Japan and need to find out if I will be able to source parts or if I will just have to use the car as a parts car. I have tried to source a replacement transmission here but haven't had any luck. Thanks in advance for any help.
