06 f150 4.2 changed the transmission and now the trans fault lights on.Also not getting any readings on my 02 sensors. Ive checked fuses and any obvious grounds i could see.

P0134 is for #1 o2 sensor no activity. Google this for good info. Maybe you have a broken wire or bad plug. Did you inspect the plug pins going to sensor 1?

check the trans fluid level, change fluid if not been done in last 30 k miles , also have the OBD codes read as may be a sensor at fault but check the fluid first

Transmission gear assembly and transmission needs inspection.Also check the transmission fluid level.Also is the fluid getting leaked or its low.

There are few very helpful links with solutions to troubleshoot these problem.

Hello
The engine and transmission in this cars drivetrain is fully electronically controlled by a computer called the PCM (Powertrain Control Module). Whenever a problem like this occurs the computer stores a record of the problem in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s)

First check the fluid level on trans dipstick while engine is running,on flat ground and in 'park' a low reading may be the cause.I always like to change the fluid and filter when I have a transmission fault in the shop,but normally I wait until fault is located so as not to throw out the evidence(but I recommend to do).This type of fault is usually caused by dirty fluid in the trans not allowing valve body to function correctly, or a fault with the electronics,they being usually a speed sensor on the trans, or the throttle position sensor(tps)on the engine throttle body,It is better to have the vehicle engine and transmission computers(ecu)checked on a scan tool for any fault codes logged,this will save hours and $$.check around there are a huge number of scan tools out there for the home handyman(just ensure it does your car type),or check out the local garages,Prices can vary for this service,but it is quick and easy to have done. Prior to fault was there any work done on your car?I often get them in with plugs not reconnected or damaged by messy workmanship.A WORD OF WARNING! Do make sure that you have the correct trans type fluid for this model,most take an atf 3 type but some are cvt trans and they do not run on this fluid at all!trans codes should be on the vehicle ID badge.

Sorry, they are not related.
O2 Sensor has to do with the fuel and emissions of the vehicle. Usually the O2 sensor replacment is a simple job, much like changing out a spark plug. the sensor cost about $35 part only. But there are 2 of them. Your mechanic or part shop can test them.
The check transmission light could be noting more that low fluid. Haw you had the vehicle in to have the scheduled transmission oil change?

P0146 pd means pending code
Pending codes and DTCs? Posted on November 12, 2010 by fcrmaster
When reading codes from your vehicle the fault code reader may show them as pending codes or normal Diagnostic Trouble Codes (DTC).
Pending codes (also known as continuous monitor codes) will be registered when an intermittent fault occurs. If that fault does not happen again after x number of start/stop cycles, the ECU will erase the code from memory. If the fault is persistent it becomes a DTC.
If you have read pending codes it is advisable to check the codes again after a week or so. If there is no apparent problem with the vehicle it is safe to erase the codes too and check back. But always make a note of any fault codes with the date and mileage of a vehicle.
If the codes read include a DTC then you need to investigate further. This you can either do yourself or advise your garage. If, again, you don't see an apparent problem (depending n the severity of the code) with the vehicle you can note the codes down and erase them. Then check again after a week or a few days depending on how often the vehicle gets used. If a repair has been made (previous owner) the DTC may just not have been reset after the repair.
The other numbers behind the code 01/06 , 02/06, 03/06 , 05/06 ,04/06 These don't mean anything . cheap code reader .

DTC P0146 HO2S Circuit Insufficient Activity Bank 1 Sensor 3
DTC P0171 Fuel Trim System Lean Bank 1
DTC P0174 Fuel Trim System Lean Bank 2
Sorry but this is something you should take to a qualified repair shop that has a diagnostic tool that can view sensor scan data.
