first off bro do not put stop leak in anything.... **** that ****, anything quick fix normally is ****.

how did you add tranny fluid and why? was it low?

were did the coolent come from?

With the description of the symptoms being as vague as it is, any diagnosis is going to be a real crap shoot. Try using clear and concise sentences, with details, and you may receive good answers.

ok lets try this again ....i drove about 12 maybe 15 miles and it ran just fine parked the car sat for all of 20minutes and proceeded to drive home i took the streets back fwy their ..while driving the streets about 10miles into the trip the car wouldnt shift in to 2nd. normally around 30 32mph it'll shift n jump up to about 41 or 43mph when it gets to 27 u hear the motor screaming as if its gonna shift it carries over to 33 34, even got it to 42 and it sounds as if im jus mashing the gas but it wont shift into 2nd when i stopped the car thinking that would help i noticed smoke popped the hood and seen my coolent was bubbling over thru the cap ...i had to let it cool n sit the next day i filled it up with coolent i once had a tranny leak the oil lines werent tight enough so it would drip wen i start the car or sit n idle for 2 long it made a grinding sound coming from the trans so i added tranny fluid i bought the fluid from autozone the following day after jus letting the car sit n cool off so my heads wouldnt crack after adding coolent ...when i started the car the next day after adding the fluids it still wouldnt shift in2 2nd it ran a lil smoother but wont shift over so i parked it popped the hood and ran the motor for all of 10minutes when i noticed from the passenger side top right corner area of the radiator smoke fumes ..it was real light if the hood was down i wouldnt see it kind of like a puff from a cigerette light n vaige and my water pump was exremely hot 2 the touch ...hope that helps with the description

1. Thermostats cost about $12-$15.....swap in a new 'stat' before messing with the waterpump.

2. If it ain't leaking then don't mess with the radiator. It's highly unlikely that a clog in the radiator will occur......at least, not to the extent that you will overheat the engine.

3. And for God's sake.....DO NOT use any of that "Stop Leak" crap even if you do have a radiator leak......unless you really want to fvck-up your cooling system !

4. Can't help ya with the tranny issue.

X2 on what KW mentioned and be SURE to follow the stickies on how to properly bleed the air out of the cooling system.

the thermostat works it shows my motor getting hotter n hotter when it over heated it was sky high and slowly lowered as i twisted of the coolent cap more n more i had to slowly twist of corse so it wouldnt jus explode with shooting coolent everywhere sounded like a tea kettle for about 20 or 30 minutes the radiator isnt leaking but it does start to smoke not heavy looks like someones buring an insent and bigwolf im in los alamitos right behind the 605fwy katella and noel
