2005 Mitsubishi lancer es transmission shifts harshly into reverse than stays in 3rd gear going forward?

SOURCE: transmission error code P1750

Might be really simple - but EXPENSIVE! I had a similar fault - apparently the first planet set breaks up. Cure - a new box. Price - crippling!

Don't be tempted to skimp on the box. Get a rebuild from a reputable supplier. A s/h box will set you back around £5-600 in UK where a rebuilt (guaranteed) will be more like £1800. The thing with the cheap box is it costs about the same to fit but you don't know how good it is till it's too late! Then you're still shopping for another but you're £600 lighter!

Also, you could be buying other faults. If the speed sensor has had a problem - the box will change badly (snatching) and that will be another £250 where the expensive box will have ahad one fitted!

I have the same problem on my 2005 cts. The shifter fork has two rubber bushings that attach at the transmission that break or give way. I assume they did this for a softer feel and to avoid vibration but it leads to the selector not engaging well when you go the extreme direction of reverse on the shifter as there is too much deflection. I replaced the bushings with washers as spacers and it seems to work as a "McGyver" fix. I do intend to get the parts needed from Cadillac to restore it to factory standards. Hopefully they have the parts. To fix the problem you have to go under the car. To get good access you have to disconnect the exhaust and the driveshaft. I did it without this and just tormented my poor hands but I wasn't willing to do all the other work while in my driveway. You simply take the clip holding the fork shaft onto the transmission selector end off and slide the small shaft out. I also took off the shifter side of the fork to study the thing a bit better. That takes a 13mm and a small allen wrench, 4.5 or 3/16, can't remember. Then replace the bushings or do as I did and stack some washers so as to get rid of the slack between the inside of the fork and the gear selector on the transmission. Assemble and try. If you have as good dexterity and tenacity at your fingertips as I do, you'll curse the day you attempted doing this without taking out all the other stuff. If you don't, take out all the other stuff to make room for your hands. The space is very confined. Good luck.

SOURCE: E40d trans will not shift into 3rd or 4th gear, only rev. 1+2

check or replace your thottle position sensor tps that trans needs to know where the throttle is to shift if it is bad it will do as you say wont shift to third
another telltale is it will act like it goes into lockup when shifting into reverse and stall the engine
