Engine was replaced still rough and tranny problems. on 2000 Ford Ranger

when i rev the engine then let off, it has a knocking sound. Only does it when reving the engine. Also, i only had drive and reverse so i replaced the shift cable because it was broke and tried adjusting. i got more gears but still no first gear and it rolls while in park. i checked the fluids and since it had been sitting for about a year, i added some transmition conditioner. still no luck. it also slips a little around 60 to 65 mph. any suggestions?

Good grief; where to start? The engine - did you have a reman or used unit installed? Knocking is never a good sign; I would check for a warranty with the unit you installed. Shift cable and transmission - sounds like you have some issues there. You should be able to adjust the shift linkage to catch all gears and engage the park lock. The internal issue with the slip around 60-65 - there is no transmission shift scheduled around then, so you could have a worn overdrive band, or a torque converter clutch that could be failing. Way too hard to know until you test it with the proper transmission tester for this unit.

The "park lock" part of the shifter mechanism; If the cable is adjusted correctly, the shifter should lock in the park position.

Dave's assessment is correct, for the engine knocking sound it could be a bearing problem and or more serious internal engine problems. Best have someone "trained" figure out if the noise is upper or lower engine related and judge the seriousness of the noise, they would probably then suggest physically checking the engine oil pressure and maybe changing the engine oil and filter as a matter of course. For more engine or transmission information, Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
