So our mechanic friend put in a new radiator then drained & refilled the transmission fluid (we've since learned that the transmission should have been flushed too but oh well). It ran great. No more shuddering. A month later they drained & refilled the fluid again. Still ran great. Thought he was in the clear.
Okay so a month later, he's driving and stops at a light and hits the gas & there's barely any acceleration, very sluggish. Stops again & when he tries to start it, nothing. No crank, no start. The battery is good (brand new). All dash lights are on.
Our mechanic friend comes to help him & finds the A/T ECU fuse is blown. He puts another in and the engine starts but the fuse blows as soon as he turns off the the ignition. He puts another one in so he can make it home. It ran but it was barely going like it was stuck in a low gear. Same as it did earlier, extremely sluggish with minimal pick-up.
He gets it home & the next morning our mechanic friend comes to check it out & needs to pull it into the garage so puts a new A/T ECU fuse in thinking it would start again. This time the fuse doesn't blow & the car doesn't start.
He checks the codes and gets a P1212 (SRS- that light has been lit up on the dash for quite sometime. Even the Nissan dealer couldnt explain why it's on) P1610 & P1612 NATS Malfunction, P0462 Fuel sensor error, U1000 CAN* Comm Circuit & U1001 which isn't listed but I am assuming is also CAN related.
The last A/T ECU fuse he put in when trying to get it going was a 20 amp and the original was a 10 amp. I don't know if the higher amp fuse or maybe his driving it home (15 miles approx) is significant to the whole scenario as to why it won't start now. Also,when the ignition is turned on, there is no A/C or heater blower, the security light stays lit, no reverse lights and a weird faint clicking coming from the fuse/relay box.
Our mechanic friend says the TCM is fried and needs to be replaced or replace or rebuild the transmission. I'm not convinced. Why are none of the codes he pulled transmission related? IS the no start issue definitely transmission TCM related or is it something else maybe electrical or IPDM related. I just don't want him to replace the transmission and it still not start afterwards.
Also, is there any other transmissions besides the 05-07 4x2 pathfinders & xterras that are compatible with a 2007 Nissan Frontier Crew Cab SE 4.0L V6 4x2 w/out off Road Package. Or is there a way to modify a non compatible model year to make it work in his model?
The salvage yards want $2000 or more for a used transmission out of a wrecked truck Not even rebuilt or re manufactured.
I think that is unbelievable.
Sorry for the novel. Any thoughts or ideas would be greatly appreciated.
Thanks for reading !
