DaveT Posted October 23, 2005 Share Posted October 23, 2005 I was looking through my FSM the other day, and saw the section on the 4 speed AT. All my Loyales & GLs are 3 speed AT. The ratios are just a hair higher on the first 2 gears, same on 3rd, and 4th looks like overdrive. So if a swap a 4 speed AT into my car: 1. would I notice a difference in acceleration?? 2. get better milage on the highway? 3. have more or less reliability? What car was the 4 speed AT normally in? Thank you, Dave Quote Link to comment Share on other sites More sharing options...
suberdave Posted October 23, 2005 Share Posted October 23, 2005 as far as i know the 4eat only came in turbo wagons and XT's, it is an electronic shifting trans, so to transplant one in to a car with a 3at you would also need the Trans computer and wireing. dont think it would be an easy job.

Turbone Posted October 23, 2005 Share Posted October 23, 2005 The XT6 AT is 4EAT. The swap would be pretty major, besides the TCU you would probably need to swap the tranny x-member and driveline. Quote Link to comment Share on other sites More sharing options...
