You will need new seals and shims.

The below thread can give much more info about this

I think you have your data flip-flopped:

I just wanna know the performance isn't too far behind (atleast forever behind) the MT. I just see so many tuners, and videos, and owners in general using the MT platform specifically and feel like the AT is just swept under the rug. I get it. This car was meant to be MT. It just sorta sucks we get such little "support" I guess.

By the way anyone know how much more the AT weighs over the MT?

I want to chime in and say I like the way the AT drives (though I drive MT), it's good at torque conversion and shifts very quickly.

gah! Thanks for the heads-up.

my 86 is MT , i drive it in highway @ 140 km , the RPM rev @ 3.700 and i think the AT will be @ 2.800 !!

At 75mph I believe my auto is right around 2500 RPM..

This car is my daily driver, and I don't miss stepping on the clutch while stuck in traffic.
On the track however, I wish I had that third pedal. I have already done the final drive mod (4.556) which helps a lot, but powering out of turns with a torque converter just sucks compared to a high performance clutch. You do however have the consistency of shifting. I've seen a lot of MT drivers miss shifts on the track.
During our Dyno day, the MT cars had a 10-15whp difference on the AT cars. Until we get that high performance torque converter, that will be the glaring difference between transmissions.

How does the auto adjust for the different gearing of the final drive? Do you have a tune? I'm very interested in doing this some day. I drove manual the last few cars, and like you I thought the auto was pretty good for what it is. Thanks for any info!

Mike, the auto adjusts fine to the final drive. It did not confuse the ecu in any way. I did before my tune so I got to drive with it untuned for a few months. I did a review of my final drive install in my build thread if you're interested.
