Help!!! I bought my Grandson for graduation a used Nissan Frontier 2008 – beautiful – knew the person got if from, it had been a one car owner had he car fax ran and he maintenance all the time, every three months saw nothing wrong. I bought it from a partner of our company that bought it from him in N.C.
It would not pass inspections so he used his mechanic and it passed, I also told him when I hit about 40 if kinda hesitated or something and sounded like mufflers may be loose. He had checked said nothing wrong. I also knew another mechanic and had him look at but did not drive and wanted to purchase it.
of course I did not sell it was my grandsons and he loved it. It was not driven a lot due to the fact his job took him out of town a lot and I took him to work a lot in my Jeep. so I guess it may have sat several weeks and he was driving and it did not want to pull up the hill. When you would mash the gas it still did not want to go – then it stopped. I called my cousin which used to be a big truck mechanic and he came and looked at it and said fuses flown.
We got it cranked and went to buy more fuses because little did I know it had many. We probably drove it 5 miles all together but did not cut off. When we had to stop at red lights it would not hardly go then ran ok same thing at every stop. When we got it into the yard and cut it off, it would not crank back up and we changed the fuses a couple of time but kept blowing. I called a reputable mechanic and he travel to you, so he came down and said transmission, which my cousin had already said. so the Mechanic said he would have to take to his shop to fix, but before he left he said what he would charge to replace the transmission that it had the strawberry milkshake transmission problem a lot of the Nissans’s had and he showed me the pink milkshake coming out of the radiator. he said he could replace and bypass the radiator, flush out and fix so this would never happen again, if there was an additional problem it would be the radiator. Well about a month later he text me (does not like to talk) and said I needed an ECU (like I knew what that was but my cousin at Nissan told me and quoted me his price of 659, rang it up to bring to me because the other guy want over a 1000 so I sent him a copy of the receipt and he said wrong thing that he had been working on it all day and that he had done another full day of testing and the EMC was going off line due to the TCM killing the CAN network and that the preliminary testing pointed towards the ECM being dead and CAN network diagnostic is very time consuming and sometimes elusive. Then he gave me a part number so that it should be the correct part this time????? Really if I had of let the other pat that was not the correct part come out of the warehouse I owned it, no taking back the dealership. So his Uncle runs a large truck lines and was sending him to school to be a large truck mechanic and he decided to be a regular mechanic and I trusted the guys, by daughter works for the owner of the truck lines and they all used this guy.
so now the truck has a rebuild transmission, he bypassed the radiator, flushed everything and needs for me to pick up a cheap 859 part at Nissan because I can get it less it happens to be since he would only give me the part number the Transmission Modular or Computer??

Help, he said I will put it on free well I am already almost out of a vehicle a month and a half that was only going to be 3 to 4 days and he god mad and said he would have put a used one that may only last a couple of months if I had not known his uncle, that made me feel even better about him, what does he really do to people that do not know hi, he talks a good story, but back to the point he wants me to get part he will but on free in one day and I do not have to pay him anymore money, I am already at 2700 plus with a rebuilt transmission that will not crank the truck so do I go buy the 800 plus part and let him do it or give him 1500 what I could have gotten a transmission fro and take to the Nissan Dealer, oh year he can program for $20.00 and will do that free, how nice. Help I know you men deal with things like this every day and I am woman and I had to be screwed over, could someone give me advise let him fix it buy the part and pray that is it or take to Nissan and he said if there was a recall or Nissan would reimburse me he would help fill out the paperwork.

Please would someone talk to me about it or just write your advise other than I am stupid, I already know that but how much is Nissan going to charge at this point. Plus another wrecker charge

Thanks for letting me get this out of my system !!!!!!!
