I've done them. You will need the transmission w Torque converter, CV axles, brackets/mounts, flexplate (for model year), TC bolts (high grade), Trans mounting bolts, shifter, trans selector switch ( rewire here), larger brake pedal, oil cooler/radiator, hard trans lines (you can make them), oil cooler hose, clamps and a wire to the ECM to activate the TC clutch. Finally you will need the ECM for the automatic or at the very least a chip with the automatic program on it. It is not a real hard job but I would not call it easy. The car must be lifted and the cradle dropped. Working alone, I would estimate 20 hrs of labor. Please work carefully. We already lost a member here this year from a car falling on him.

There is also the automatic steering column (and the interlock cable); this one has the capability to block removal of the key unless the shifter is in Park.

On the recent conversion that I did the column was left alone. Saw no reason to change steering columns and add more work to the process. The manual cars already have a locking steering wheel. The whole lockout system is just feel good security . Its not going to stop the professional.

just wanted to say cograts to you, all the pain in the butt clutch problems will be a thing of the past
And as a bonus you likely caused a lot of guys who did (or wanted to) do a auto to manual swap to say "SOMOFABITCH!"
so what are you doing with that highly desirable (sic) Getrag (should have been called Getrags, one rag has never been enough)

I've been an automatic man for many years going back to my drag racing days. No human can shift a Fiero as fast as an automatic can but the stick guys say shifting through the gears is fun, that is until you get stuck in stop and go traffic for an hour..

All my vehicles I've owned since 1972 (Ford Mustang 1966) have had manual transmissions, other than replace the Mustang's tranny with a rebuilt (why I only had to pay $200 for a fairly pristine one) I've never ever had to bleed , replace a clutch, or do any tranny work EXCEPT for the highly desirable Getrags

My Vette has 6 gears, a genuine pain in rush hour which is why I almost never commute with it, I did finally get an SUV with an a CVT and paddles which I almost never use, the exception being to use engine braking in winter on occasion rather than the brakes

today a manual transmission is like a corded phone or a VCR
if I bought another Vette, it certainly would not have a manual transmission

Love my corded phone. Much better sound quality than a cell phone, and no "network" issues.

And oh yeah, automatics suck.

I don't think that cellphones must inherently have worse sound quality (with 21st century human knowledge, we should be able to best our predecessors)... though I do think that today's consumers expect low prices and disregard quality. Companies optimize between price and quality to align with customer expectations.

How is it that a 1984 Fiero ECM can still run its engine acceptably well on its original chip, while a brand-new smartphone is released with flawed software and needs constant software updates? I blame the consumer.

I wish that we were able to race so that I could prove you wrong. I can reprogram my PCM to control the 4T65eHD for any shift point and any style of driving. If you are referring to the TH125; a three speed auto is certainly not ideal but many have had success racing with a modified one.

Dennis, my comment was a tease and made in fun... but with fun in mind, you'll never convince me that an automatic is more fun to drive than a manual. Sure, an automatic may make stop and go driving in heavy traffic more tolerable, but at any other time, a manual is much more enjoyable to drive.

It doesn't take listening to too many radio interviews with guests on their cell phones to realize how poor the sound quality compares to a landline. Even when the signal doesn't drop out entirely, often the vocals become totally distorted. Sure, in theory, modern technology can give us pristine sound/audio quality with cell phones... but in the real world, it actually leaves a lot to be desired.

We are the guardians of a dying art. The purveyors of a craft born of necessity, but beloved for its spirit. We travel with purpose regardless of our destination. Every corner an opportunity for the perfect downshift, every stop a new starting line.

when you say rewire for the trans selector switch? do you mean on the engine harness? if so I used a auto engine harness but didnt change the interior harness. the car is all done and just waiting to start it up. right now it doesnt start. I have power on the interior but only on the radio and HVAC, dash has no lights, turn key nothing happens. I did move the 12v power from A4 to E2 on the engine harness as I read that is required if you keep the manual c500 harness.

I believe I have something not connected right on the auto brake pedal that was installed? it had the 2 pedal switches on it when I got it so I just plugged them in thinking that's all that was needed. the original clutch safety switch was cut and the purple and yellow wires soldered together. I did install a auto steering column as well.

For those of you tech guys, have I missed something? I did notice that my ignition key will turn but when I go to turn it off it goes slightly past the point where it should stop to remove the key. when this happens the interior lights come back on as well. could my ignition switch on the steering column be bad? do I have the pedal connectors hooked up wrong?

one other thing, I converted to a gen 2 headlight wiring and module. I flip the headlight switch and the headlights go up perfectly, hit the switch again to put them down and nothing, not even a sound from the motors.

any tech help with pictures and directions would be great.

You aren't getting a start signal to the starter solenoid?

Try adjusting the neutral safety switch on the transmission.

Goss I didn’t set that to factory reset when I installed it. I’ll do that and see what happens.

Loosen the two bolts on the NSS, have someone hold the key in the START position, and rotate the NSS slightly until the starter kicks. The NSS will allow the START signal in PARK and NEUTRAL only.

Once you find that spot, put the shifter in REVERSE, key in the ON position, and check that the backup lights are on.

If everything works as it should, tighten the two bolts to secure the NSS in position.

Frig. I did a bunch of adjustments on the steering column Ignition switch and the NSS. At one point I got the starter to engage a couple times while fiddling with the shifter but I couldn’t get it in the right spot. Well I know it’s probably the nss adjustment or it’s bad. And now I k ow my starter needs adjustment as well as it’s just spinning and not cranking. I’ll leave it for another day now.
