Question:

Is there a difference between a transmission computer and a transmission?

I‘m looking to purchase a car from a private seller and he advertised that the transmission needs work or just replaced. I‘ve only searched online so far, but I‘ve been seeing a lot of transmission computers for sale? Is that the transmission? Or is it just a component to a transmission? I always assumed that it was something mechanical, but I‘m not sure of the difference.If I need to replace the transmission on a vehicle would I buy a transmission computer?Please help, I am totally confused.

Answer:

The transmission is a control unit for the transmission. It does things like to tell the transmission when to shift gears and how firm the gear shifts should be. The transmission is the actual mechanical assembly with a series of gears and clutch packs that actually changes the gear ratios of the transmission output. Before even considering this purchase I would want it completely verified what is wrong with this car. The transmission ot the transmission computer. This would make a big difference in the cost of repairs and my offer for the car would reflect this difference. If you are still confused, walk away and look for a different car.
A transmission computer controls the transmission. Like a the brains of the transmission. Computer $300 Transmission $3000
