Re: My lucida struggles to find gear and engine races...
How often have you had a tranny service done on it. if you never had the tranny serviced then sorry to say this you need a new tranny. your tranny is about to stop working all together soon.

Is it possible the clutch pedal is interfering with the throttle? Start the engine in neutral and allow it to idle. Press only the clutch pedal down and see if this increase the engine speed. If it does speed up the engine and slows back down when you release the clutch then somehow this operation is where your fault lies. If it doesn't alter the idle speed, then rev your engine and release the throttle to see if it returns to idle immediately. If it is slow to return to idle then your throttle cable could be sticking. This means when you change gear lifting off the throttle has little effect and depressing the clutch to change gear causes the engine to race as the throttle is still partially open.
The problem concerning low gear locked up sounds like a bad primary shift solenoid (located on the valve body internally) the other issue with the forward gear only engaging with the rpm up to 1800 could be inadequate hydraulic pressure (a transmission front pump issue), most likely there is no problem with the pump if when shifting the selector lever into reverse it engages quickly and normally. This may be a transmission computer issue and I would recommend having the dealership do a diagnostic check on the transmission to eliminate the computer as a culprit. transmission problems are very difficult to figure out and before spending a lot of money get the electrical diagnostic done first.
My gas petal used to stick on the jeep so i spray up in there on the petal to stop it from sticking ore the brake light woud stay on becuse petal got stuck try some WD40 just dont sray on your petal ok might work
With all you've done so far I'd have to say that I'd be tempted to take it to a good tranny shop just for sake of a diagnosis, which the mechanic can probably do free of charge, and a little drive down the road. Almost sounds like it's trying to take off in second gear or something. Other than that, the only thing that comes to mind at all is possible plugged exhaust, like catalytic converter.
The vehicle is just shy of 1900 Kg (lets say 4100 Lbs) and the engine and transmission have got to be at least 550 but lets say 300Lbs just be on the safe side. So, I'm thinking you should be fine with an estimate of 3800 Lbs
sounds as if you may be looking in the wrong spot. If different gearing is drastically changing the symptoms you may want to check the trans. or torque converter. sudden pop with engine rpm increase and lack of power sounds like possible band breakage in transmission or impellor breakage in torque converter.
