Already took it to the dealer. They said the warrenty is voided cause I didn't service the tranny at 30K miles. Its got 37XXX miles.They said I need a new transmission because the oil is burned up. Service Manager is going to try to push it to get it covered under warrenty but isn't promising anything.

 

NISSAN TITAN, transmission shudder, 3 x to nissan, they "RECOMMEND" a new torque converter and transmission, when I asked why they said they are one and the same. When i called BS they said "we recommend a new transmission mission" first 2 trips there was no code and now they say say code P1867 which I can not find anywhere online for nissan, but it is a code for a ford 150/250. any one been lied to?

 

So I had this shudder in trans on 2017, took to Nisaan 3x as previously posted. First 2x no codes, they did nothing. 3rd x they feel shudder and then tell me I need a transmission at $8404. I had been saying to flush or change torque converter. I got some story about the torque converter is the transmission. They think when they see a "retiree" it is a gold mine. I asked what was wrong that I need a trannie. they said it is shuddering and no way to fix. So I take it to a local trannie shop and the fluid is blackened not burnt. As you all know there is no dip stip for the tyrans on a 2017 /I asked them several times to perform trans TSBs everyone here posted. nope, they want $800 to do that and they say it wont help. okay back to the shop, they drained the trans, flushed and charged me $660. Yep $660 and the thing runs better than I ever remember. It was fluid, fluid, fluid. CHANGE YOUR FLUID EVERY 30K. What a rip off ... so now I am writing Nissan, no Amer, the dealer, local news outlets (all3) and consumer advocate at state level and DAV. F'ed with the wrong Marine! this may go nowhere but I sure hope it gets on the news.....

 

The torque converter is a huge problem on the aramada, which uses the same engine and speed as the early second gen trucks. Have them scope and see if your is cracked or bad

Glad it was a simple solution for you. I'm glad you came back and posted a solution that worked for you so others can find it also.

Reason 10,245 I won't take my truck to the dealer. Clowns that know nothing other what the code says. Part changers, that can't do that correctly.
