Had replaced plates and lining of the automatic transmission of lancer glxi '95,yet after putting it back, reverse gear not working. does it something to do with the torque converter or still with the transmission?

You have to have the synchronizer gear replaced.

is this a manual transmission ? You may have a problem with the clutch plates, clutch cable or if hydraulic the clutch master cyclinder .
The clutch is two plates of metal that rub together to allow the gears to move the car. When you push the pedal in the plates come apart to allow you to change the gears. If the clutch plates wear out or do not touch the gear box will not go into gear. It will feel like something is stopping the gear from going in. It could also be a syncromesh problem. I have a car that intermittantly does not go into reverse but I put the clutch pedal out and back in and it goes away,

It is not the TCM, it is a failed transmission.

Maybe your differential is shot and will only allow reverse spin or the transmission was not really rebuilt professionally. Was the transmission checked outside of your car after rebuild? Does your vehicle have a Powertrain Control Module (PCM)? Maybe the module went bad or faulty.

This will help.

Thanks.

The high viscosity ensures transfer of lubricant throughout the gear train. Some modern automatic trans-axles (integrated transmission and differential) do not use a heavy oil at all, but lubricate with the lower viscosity hydraulic fluid, which is available within the automatic transmission.

automatic or manual transmission? if manual then the first gear fork is bent if automatic then there is trouble in the valve body which means that you have to have the transmission rebuilt

check/replace the fuel filter. the fuel pump is defective.

Have you Had the transmission fluid checked? It sounds as if the transmission is slipping in these gears which would point to a fault within the bands. To have a problem like this repaired could cost as little as $200 or as much as $1700 depending on how much needs to be done. Was the replacement a second hand transmission? If yes then did you have a warranty period with it? Let me know and I will get back to you as i am about to seek out a manual for this.
