Automatic transmission won't do anything
88 GXL N/A
Transmission was running perfect before rebuild.
Hey, just put my rebuild in. She runs and all... but when I select a gear on my automatic transmission while running I just hear the noises you'd hear when the engine is off. You know, just the sound of it moving the internals. I don't hear any chattering, or clicking, nothing grinding, no bad sounds from it. It's just not engaging in R or D, 2, 1. It stays put in park and it rolls in everything except Park. Sounds like I don't have something plugged up that engages the gears, but Im having trouble finding my mistake
Tachometer works too, so I know that's it's turning the internals of it.
Any suggestions would be appreciated

ok, my fluid is topped off. it still won't do anything. the shifter will move around, but it won't go in gear. when i move the shifter into a selection though, my engine revs down and acts like the transmission is engaged. what could it be? open to any suggestions, i need to get my car out of my grandparents garage and over to my house down the raod

not trying to criticize, just trying to narrow it down:
if the linkage wasnt connected, how would it stay put in park, but roll in the other gears beside that? could the linkage have "fallen out" with the engine out? i didnt take the transmission out, just the motor.

Yo this is ken who came with dave and steve! u but the torqueconverter on the engine and not on the trans. shaft as u should! there are two notches on the comverter where it meets the pump u grinded them off! ur chances of getting those connected with the converter on the flexplate are one in a million! u need 2 pull the trans and u'll c what i'm talkin about....where its grinded off!!! This isn't only a must on 7s its other cars 2 i could tell u horror stories about people trying 2 save a few hundred bucks and pull the trans and have it rebuilt and (put it back themselves)...get it in and the same thing that has happend 2 u!!!!!!! and the grand they dropped in the trans rebuild....gone!

dude are you serious? i had it lined up PERFECT.
i guess it's time for a 5 speed conversion?
but i don't understand how it would get a tach signal in the transmission, but not turn the gears. anyone help me with this one?

Maybe you're using some kind of tach method I'm not aware of. But your tach signals work off the ecu which I think is taken from the coil. No where is the tach an indication that the internal workings of the tranny are turning.
You should look up and understand how a torque converter works, which is what I was going to suggest too.
Not trying to be a smart *** and act like you don't already know..... But it would seem to explain some of the difficulties you're experiencing.
For instance a torque converter actually powers your car. Its the intermeidary that translates the engines power into useable power for your auto tranny to give power to the wheels. The converter does this by changing the direction of the fluid traveling though its stator so violently that this motion is what is responsible for making your wheels turn.
So obviously if something is wrong with the converter's natural operation, you will go no where.

oh, i had read somewhere that the tach signal on the rx-7 comes from around the middle of the transmission. i know there is a signal from the coil, had to use it for my remote start system.
I guess it's time to pull the engine and trans out, inspect them, and probably end up doing a 5 speed swap.
Ken do you know of any 5 speed trans for sale in your area?

the speedometer reads off the transmission, not the tach.
When you put the torque converter in, did you seat it properly? There is a measurement that you have to take to make sure the thing is fully seated onto the transmission input shaft. Its called "dimension A" in the Haynes manual and Factory service manual. I think that is what NCTII87 was talking about.

missing clutch pedal? an automatic doesn't have a clutch
i meant by 5 speed swap, that i'd swap all the necessary parts including the clutch pedal assembly into the car.

Now the speed signal comes from the cluster which the speedo cable comes from (the other end of the speedo cable is attached to the tranny).

I need help with my AT as well. It seems as if there's slippage. First gear won't engage fully with 2nd. 3rd & 4th are fine. How would I do a 5spd conversion? How much parts and $$ is involved? Oh and here's the kicker: I'm located in Italy & there aren't that many Mazda places around here. Any tips? Any European places? I'm willing to travel to nearby countries. MY FC IS WORTH IT!! 
For now I'll try to change the fluid and see what happens, but a 5spd would REALLY kick some b*tt. LOL!

You may have damaged the front pump on the transmission when you reinstalled the engine. If the torque converter is not completely seated into the front pump, than forcing it together while mating the engine to the transmission will cause damage to the pump. Sometimes these are a bit tricky to reassemble correctly. If the front pump is damaged, that there's no hydraulic pressure and the transmission will not function since the transmission is essentially a hydraulic device.
