What would cause a tranny (5 speed manual) to grind into gears and also be harder to shift in colder climates until the tranny and motor are warmed up to normal temps?

Oh and also kinda sound like running water when im crusing down the road coming up from the shifter

Its not a honda its my 89 ford ranger!

 

bump

 

bearings or something of that relm i would assume. i dont know much about fords
