I have a 2014 F Type S V6 convertible with 17k genuine miles on it.
I've noticed recently when reversing off my driveway, reverse works fine on the level but my driveway slopes down about 15 degrees at the end where it meets the road,
As soon as the back tires contact the road, reverse stops working.
I think this might only happen when cold but curious to see if anyone else has experienced this?

 

I don’t have any deep direct knowledge to offer, but my butt head googling skills are up there ;-0 —>

An automatic transmission that won't reverse on a hill often indicates
low transmission fluid, a failing torque converter, worn clutch packs, or a faulty shift solenoid. The steep angle reduces hydraulic pressure, causing the car to struggle or slip. Immediate steps include checking fluid levels and scanning for fault codes.
Potential Causes for Reverse Failure on a Hill:

• Low or Contaminated Fluid: The most common cause, as reverse requires high pressure.
• Worn Clutch Packs/Bands: Specifically, the reverse clutch pack may be worn out.
• Failed Shift Solenoid: A faulty solenoid prevents the transmission from shifting into the proper gear.
• Faulty Position Sensor: The sensor fails to tell the computer to engage reverse.
• Broken Gear Teeth: Internal damage to the reverse gear mechanism.
• Shifter Cable/Linkage Issue: Stretched cables can cause incorrect gear engagement.
  

Troubleshooting Steps:

1. Check Transmission Fluid: Ensure fluid is not low or burnt.
2. Scan for Diagnostic Codes: Check for solenoid or transmission faults.
3. Try Neutral-to-Reverse: Move the car slightly forward, then shift to reverse on flat ground.
4. Check Shifter Cable: Inspect for damage or loose connections.

 

You didn’t really offer information around whether it was manual or automatic.

 

A '14 would automatic, wouldn't it?

+++++++++++++

Does reverse provide DRIVE if you approach the driveway apron at a 45 degree angle?

 

Oh, perhaps…Admittedly, I’m not up on the nuances of what years had manual vs. not, so I’ll take your knowledge on that.

 

Manual came out in '16. That's one nuance I'm quite familiar with
