I thought so too on the SMOD but there was mixing in the fluids so idk what happened there. The previous owner also tried to pull a fast one and swap the fluids before selling it to hide the issue from me (why is it so hard to be honest? I would still have bought the car because I know how to fix the issue lol). Upon further research, I have a feeling there's a shift solenoid or two that have gone out. It's at the mechanic right now and they're taking a peek. Normally I would try and mess with it but I'm working 7 12 hour shifts rn so I really don't have time unfortunately. There's a few cat codes and the fuel level doesnt work, which also has a code. There's one code that's thrown me off. P2135. Throttle position sensor A/B Voltage correlation. I swapped the throttle body and the code came back after about 170 miles, which tells me it's more intermittent than anything. This code puts it into limp mode. There's a few things it could be. I didn't go with oem for the throttle body, and I know Nissans get really mad when you do that to them. It could also be a wiring connector issue, or it could be something with the transmission. I've heard that transmission issues can throw throttle body codes. There's no transmission codes that I saw on my code reader, but I don't have a fancy shop grade one so what do I know. The car does have the manual still which is nice. I used it to find the correct transmission fluid for the swap, as well as the fluid amount.

The biggest concern I have is keeping the original towing capacity. (I think about 5 thousand pounds from what I remember?) I plan to use this thing to tow my 350z around to autocrosses, so that is really important to me. If it somehow goes higher from a better transmission, great. Lower is a no go though.

Hey there, sorry if this is in the wrong place, I'm new. I just bought a 2004 pathfinder off FB marketplace, and I love it to death. Small issue, the transmission feels like it's going out (really hard shifts in and out of second gear, limp mode (this has not happened since I swapped the filter out), overdrive gear not engaging despite overdrive being on, etc). I did swap the radiator and transmission filter with a fluid swap (NOT a flush, I know that's really bad for old trannies) in case it was the strawberry milkshake of death issue, and it didn't fix it. I wanted to initially do a manual swap, but that's not really in my budget or skill level unfortunately. I was wondering what options you can do for an auto trannie swap without too much trouble? I would prefer at least 5 gears, (the 4 speed currently in it makes the engine feel really sluggish compared to what I know it can do) but are there any out there you can bolt in and run without issue? Any help would be much appreciated, I taught myself everything I know about mechanic stuff so I don't know all of the complex things yet unfortunately.
