Depends if you have a manual or automatic. Manual transmission, no, there is no transmission computer. For an automatic transmission, the engine computer and transmission computer are one unit typically called an ECM, Engine control module. There are many different names for and ECM. Ford started using computer controlled transmissions in the early 90's and late 80's.
there is a computer for the automatic transmission but i did not think there was a relay. I would have to double check.
The transmission computer is only found in automatic cars because it controls that which in a manual car the driver controls, the shifting. The transmission computer is what generally makes a car automatic because it changes gears automatically without any effort from the driver (except of course the gas & brake).
The transmission computer is an important part of all automatic vehicles. It controls the gear changes without the driver having to manually do it themselves.
no The computer will loose all set codes when the battery is disconected for any amount of time usually 30sec to 5min depending on make of car
To change an automatic galant to a 5-speed, you need a Computer for the Manual transmission of that year, and an engine.

The engine computer on the firewall also handles the transmission.
Is yours an autoshift, or a fully automatic transmission? With the autoshifts, the synchroniser has a bad tendency to go out because of improper clutch manipulation. This shouldn't be an issue with a fully automatic transmission, however, and if that's what yours is, the first two culprits would be faulty circuitry in the transmission computer, or poor coordination between the computer in the transmission and the engine computer (this was a recurring problem for Allision automatics coupled to Detroit Diesel motors). There should be a way of reading off fault codes from the transmission, but that's going to probably require you to go to a mechanic with the necessary computer software to do such.
The problems may be overwhelming. The onboard computer may not be able to handle a different transmission. It all depends on the interconnectivity between engine, computer and transmission.
Yes u MUST change the computer if you are changing the transmission from auto to manual (visa versa). The computers are different for the especially where the trannirs are concerned.
Replace your AT Control Unit (Automatic Transmission Computer)
