2002 Dodge Neon No acceleration after stopping and alot of

My AC line looks fine to the eye so I guess it's good for now or better I'll find out how good it is when I ue the AC in the summer right? (Lol)

Canadian Tire had called me to inspect the car because their mechanic could'nt find the leakage on the car?

They had told me that my radiator had blew up and the tranny fluid had somehow mixed itself with the radiator.I opened up the rad cap and the coolant is like a strawberry milkshake consistency. Not good huh!

I was informed to bring replace the rad, change the tranny fluid, check the water pump and the tranny line for damages.

They say that there could be a chance that the mixture could've entered my transmission and if so that will be very bad news.

I bought my new rad already and will have it replaced by a friend mechanic with new tranny fluid.

My main worry is that when I was bringing the vehicle to the Canadian Tire shop when stopping at all intersections the car would not move when accelerating?

1) Is that due to the bad mixture of the rad fluid mixed with the tranny fluid?

2) I also hear a "cluncky" sound when the car does move and it will "float" at times when accelerating. Was told it was the tranny!

3) Since the mechanic at Canadian Tire could'nt find the leakage if I replace the rad, will the two fluids mix itself again when I install the new rad?

The only thing I know and saw was that a "pinkish" liquid had leaked majorly close to the AC/Tranny line"back near alternator" but can't find it anymore.I guess once I've topped everything up again if the problem still exist then I guess the same explosion can happen again huh?

I guess I should pay for a transmission diagnostic too right?

Thanks again, cheers.
