Hey, I'm pretty new to this forum (obviously). My truck 2007 f150 5.4 threw a p0717. Long story short, the sensor ohmed out just fine and everything was connected. My worst fear of needing to replace the trans has been realized. Here's my issue, what transmission do I have? It seems like it's a coin flip between a 4R75E and 4R75W. How do I tell the difference? VIN decoders haven't helped and there is no door sticker that has any type of code for my transmission. If there is an easier way than pulling it out to check then I'm all ears. Thanks in advance.

-Kyle

Google the trans code on your driver's door

 

You have a 4R75E

Model Year 2004
Information extracted from WSM page 100-00-11
Transmission Code

• A — 4-speed automatic, 4R70E
• B— 4-speed automatic, 4R75E

Model Year 2005

• A — 4-speed automatic, 4R70E
• B— 4-speed automatic, 4R75E
• M— 5-speed manual, M5R2-C

Model Year 2006
Information extracted from WSM page 100-01-8

• A — 4-speed automatic, 4R70E F-150
• F— 4-speed automatic, 4R75E Mark LT

"There is no door sticker that has the transmission code" in all actuality there are no door, pillar, or any stickers aside from the stickers that I put on

 

You are awesome. I dont know why I was getting something about the 4R75W when it seems like it's not even an option. Thank you so so much

 

Hell yeah. Now to find one for less than an arm and a leg. Thank you again

 

U-Pull yards have them for around $150 plus core. You pull but if no good you return for another.
The easy way to tell the difference between 4R70W/4R75W and 4R70E/4R75E is that the 4R70E/4R75E has a extra sensor (TSS) located basically directly above the Trans Range Sensor (shift cable attaches to TRS). Don't buy a 4R70W/4R75W and try to put into a 2007 or you will get to try again as it will not work without extensive internal changeover.

P0717 does not mean you need a new transmission. My guess is damaged wiring or connector
Potential causes for this code to set are:
A faulty input speed sensor TSS not OSS
Damaged, loose, or shorted wiring and/or connectors in the circuit
PCM failure or a PCM programming error

What tests would you recommend I do? Just for a bit of history on the vehicle. It's rwd, I have recently been having wheel speed sensor codes for the right front c1297, which I wasn't too concerned about. The abs lamp would only come on while on bumpy and curvy roads. I have recently, within 2000 miles/8ish months, done a pan drop and replaced the filter with no issues. Most recently, I replaced all of the front suspension on both sides and had it aligned. After the alignment, thats when I ended up with the p7017 and as of this morning, intermittently slipping 2nd gear. The tss connector looks in good condition and is still nice and tight into the sensor.

 

This is a complete guess
The PCM looks at wheel speed sensors and transmission speed sensors to establish shift points AND detect wheel slippage. Wheel slippage can put you into a vehicle speed limiting mode of about 45 mph. I would go to work on your C1297 problem and it may solve the P0717.
Besides the P0717 what else makes you think you have a trans problem?

One of my previous vehicles, a 1998 Lincoln Town Car, went into speed limiting mode more than once. Pot hole on I-94 near Detroit and expansion joint on I-75 somewhere in Kentucky. First time it happened I had no clue what was going on, you could push the pedal to the metal and still only do 45 mph and that's not good on an interstate. Without knowing any better or what had just happened I turn the car off and back on and this reset (cleared) the speed limiter and I was able to proceed normally.
