transmission problems

I have a 98 BlazerLT 4x4. My problem usually starts after about half an hour of driving, originally it just shifted a little hard, today the gears started slipping. Particularly between second and third. I've recently replaced the plugs, wires, and pcv valve. The transmission fluid is definitely leaking, all other fluids are good. My ses light is on and the codes are DTC1870 and P0300. I may have those prefixes wrong, sorry.
Please help, Im broke and this is my everday vehicle. I am planning on fixing this myself. Im not an real experienced mechanic but I know how to read my Haynes manual.
