I thought the same about brand new until I saw that thread on a Racetronix sending unit with a ceramic ball stuck down a tube. Bottom line is you must check everything you buy b/f you install it, even if it brand new from a trusted source.I thought it weird that a side tank could even get plugged. I haven't seen the alradco one, but even a stock rad cooler for trans would be hard to plug. And if you didn't clean out the side tank with a little brake clean first, then it's still your fault. Custom parts are just that and should be cleaned and inspected no matter what.

Hello to everybody, I am new to the forum. I own a 1987 Grand National with 26000 original miles. The original radiator was leaking so I replaced with the Alradco radiator. (The transmission acted perfectly before this radiator was installed) The mechanic hooked up all the lines correctly, triple checked them, and filled with fluids. I took my first drive with the new radiator and I think my transmission is smoked! It started with losing overdrive all together and then I had drive but it wasn't shifting smoothly. I let it sit for about 30 minutes and drove it again. This time it went into overdrive and wouldn't shift into any other gears. two days later I test drove it again, this time it would me in drive and overdrive, shift very hard into 2nd gear but i had no gears after that and the longer the car ran the worse the transmission acted.
I want some opinions please. my mechanic is telling me he thinks the transmission cooler is not working, the lines going into the radiator were scolding hot, he says that shouldn't be. The transmission fluid levels are fine and there are No Leaks anywhere. So now I can't drive the car because I think there is major internal damage to the trans from too much heat. Alradco told me that they have never had a problem with the radiators and even if there was No Cooler the transmission wouldn't overheat, I don't necessarily buy that. All opinions are Greatly Appreciated!!!
The lines wouldn't get that hot if the cooler was blocked.I don't understand; it says: The mechanic triple checked the lines, and filled with fluids. Then it says: The transmission fluid levels are fine and there are No Leaks anywhere. How did this morph into low fluid level? This still stinks of coverup like before.
Was the fluid replaced with new? Cant explain why but sometimes when transmission fluid is replaced with new fluid problems arise, maybe the experts can chime in.
I've never seen fluid take out a trans. I've serviced many transmissions. I'll take fresh fluid over old oxidized fluid anyway. If the trans goes after a service it was likely a slush box to begin with.
Id verify your dipstick and tube are correct. Being down a half a quart should not create the symptoms you experienced unless you were getting good hook with the stock pan and filter.The update, I was told that these radiators trans coolers are larger than stock and need more fluid. the Transmission fluid was between the hash marks. The rebuilder told me to OVERFILL it right to the curve in the dipstick, around a 1/4 inch over full. Amazingly after doing that I got the overdrive back and the trans was shifting again, although some slight slippage in overdrive. We did test the trans lines first, really strong flow going to the radiator, coming out of the trans cooler there was a delay but it did start flowing. So I'm getting the trans rebuilt, I was told once they slip its all down hill from there, so it will be going to long island NY for the rebuild.
