Has anyone switched their manual trans to an auto or no anyone who has. I wanted to see what was needed to make this happen.

Do you mean a stock manual to a stock automatic? That's rare.

We switched from stock 5 speed manual to 4r70w (automatic with full manual valve body). The 4r is almost standard issue for getting into low 10s and 9s. Rated to 1000+ hp, only 3 forward gears, and built strong enough for transbrake launches.

Now that car has been removed from the street, we have just switched to another automatic, the powerglide, which has only 2 forward gears.

I wanted to put a 55r55s in my car and I figured I would drop in the ratchet shifter also. The reason for this is because the cars at 550 rwhp and I like the idea of the auto with that shifter.

im still kinda up in the air about it because i have a feeling its gonna cost way to much to do something like that. So i might end up just throwing in another manual.

Auto to manual is pretty straight forward. Here's a link to a write up I did in late '05> Auto to Manual Trans ''How to'' guide - Mustang Forums at StangNet


Manual to auto is not bad either, but you'll need an engine/tranny portion of the wiring harness for certain. The manny harness can't be modified to auto without a mound of work. You'll also need to install a cooler and lines. You won't have the lockout solenoid that requires your foot on the brake to get it out of park. I haven't done one, but it can't be too difficult.

I think im gonna go with the tr-6060. I saw that steeda had a upgrade kit that came with the transmission but i need a clutch with 26 splines and is rated for 550 rwhp. Has anyone put this trans in and what clutch did they use.

If anybody want to do the manny to auto swap here's a fairly complete list of parts:

powertrain control module (PCM) for auto
transmission
torque convertor
flexplate
engine/tranny spacer plate
wiring harness
auto pedal box (without clutch pedal...I have a couple here)
shifter
cable
trans cooler
cooler lines
transmission sensors that plug into harness (may be on the tranny)

Note: You will reuse the driveshaft and crossmember. The bolts that hold the tranny to engine have a couple that will need to be a different length than what you had before. This list is pretty much complete other than some small **** like trans fluid and some minor hardware. Oh yeah, you'll need a pretty, new skirt! :D

Quick question;

I know that a MT ECU can't be used with a AT, but can a AT ECU be used with a MT?

On '05-'06 cars the MT pcm can be used. I tried to do the same in an '07 car and at the time nobody could re-engineer the thing for me. It's been a couple of years though. Maybe things have changed. The same guy I had change over the '05-'06 pcm was the guy that couldn't do the '07 for some reason.
