I just had my daughters Injectors cleaned on 04 RX-8 4 port. I put it all together and it ran like a champ! But now my daughter drove it home about 45 minutes away and it started sputtering like it was hesitant to go. Now she has no drive gears but reverse. I noticed I hooked her lines backwards going to her inlet. I corrected them thinking this was the issue, but still no forward gears and now a loud winning like noise is coming from her engine...is this s bad tranny or did I cause damage hooking the inlet lines backwards

Inlet hose diagram. The one coming from the oil inlet to the accordion looking hose is one of them.
? All fluid levels are good and clean.

 

I'm not sure how you hooked it up backwards or what that even really means, but the transmission has nothing to do with the fuel system or vacuum/breather lines

edit: manual transmission, if it's an automatic there might be more to it because I've never messed with one of those

.

 

It's a AT. One hose comes from the oil cap, another comes from the Actuator and another line comes from the metering oil nozzle and they leed to the accordion inlet pipe coming from the airbox. I had the metering line and Actuator mix up to the wrong hole in the inlet pipe. If it is the transmission does anyone have a manual on replacing a Automatic transmission?? I'm going, well wanting to do it myself, it looks like all u do is drop the back exhaust, main drive line brace and drive line and cross member brace and slave solenoid and then just unbolt and drop it...but I want to do it right..

 

I don't think that would damage anything since you still connected them to the accordion tube.

Those lines are designed to go into specific holes in terms of length, though. Maybe you snapped/cracked/loosened one of the lines when you stretched it to connect it to the wrong hole on the accordion tube?

Don't see how fuel injectors can mess up a transmission, auto or manual.

 

Which actuator are you referring to? Because the actuators would be on a post throttle body vacuum source and the other three hoses for jet air, oil injector nozzles, and crankcase ventilation (oil filler tube) are pre-throttle body filtered atmospheric air source. Those three hoses don’t care which fitting they’re on as long as it’s pre-throttle body and they can attach properly. I don’t see how you could hook any of those three hoses to the smaller post-throttle body vacuum fitting, but if you did that with the oil injector air hose that wouldn’t be good for the engine.

The transmission though, I just don’t know unless something for it isn’t correctly connected or it just decided to give up the ghost.
