Does it have a transmission cooler in this radiator?
William M April 1, 2019
Not on this year car the trans cooler is in front of the radiator. I had to disconnect the trans cooler from the radiator in order to remove the radiator
Ted T April 1, 2019
Yes
G E April 1, 2019
Yes, if this is the same radiator I ordered from A-1. It has been installed now for about eight months and I am experiencing no problems. Side note; I had to add additional transmission fluid, the shop did not put enough fluid in the transmission after installation. Make sure to check that before leaving the shop.
Wm S April 1, 2019
Yes it does.

Very helpful people
Was very happy that they sent me another radiator after the first one they sent me had a crack in the bottom of it by the quick disconnect. But that one had a tiny crack in the top of it that sprayed fluid under pressure... the service man that took my call was very nice and said they would send me another radiator after they had an expert inspect it , that was 6 weeks ago and havnt heard from them or received the new, inspected radiator.

Did not last
Well I guess there was a reason it was so much cheaper then everyone. It did not last 90 days

Quality parts fast shipping and a good guide for installation.

TOTALLY SATISFIED WITH PRODUCT
Excellent delivery service. Radiator was an exact replacement fit to original manufactured part with only one minor adjustment which required removal of plastic flashing on mounting tabs holding the air conditioner radiator. Excellent price when compared with original part. Will order parts from this supplier again.
December 27, 2018
Perfect. Great
Our car had multiple options to fit, your the only ones that had the perfect fit. And the best price. So happy to find you...

My first purchase
This was my first time ordering a part for my car. Online. I was sceptic. I looked at other prices and noticed that 1Aauto prices was the best offer. I then decided to make my purchase once I spoke to the representative who was knowledgeable about what I was interested in made the worry a lot easier. Overall the item I ordered arrived on time in good condition and I was very pleased. I will be in contact for future purchases. Thank you Susie
