Reverse won't engage 2010 auto help

[scd83]

I would love to get a second opinion but the box is out and with an auto transmission specialist so in order to get a second opinion I'd be paying labour already at least $1k and then pay for another trans specialist to look at it I just think I may very well add more to the cost than it is worth. If it wasn't such a major failure I would have been doing much more research and get quotes etc from various suppliers. The shop doing the work is a sponsor on this site so I am hoping/confident they are not taking me for a ride.

I did drive the car for a min after the warning light as I was half out of the mess I was trying to get myself out of the car did not go into limp mode.

I would love to try and chase it up with Jeep but just don't have the time, patience and need the car back on the road asap unfortunately. From what I have read I think i'll stick with current gearing and add an aftermarket cooler as soon as I get funds together.

You can't get away from the fact that running larger tyres is going to adversely affect your overall gearing. However, for such a small change it's not worth re-gearing as far as I'm concerned (and I run the same size tyres as you on my MY10 JKU CRD auto). If you had 3.21 diff gears then you might think about it, but it seems a bit excessive when you already have 3.73's.

From what you've said it sounds like the significant contributing factor is the hard beach work without an additional trans cooler.

I've still not had an additional cooler fitted to mine but it's on the list. Looking at getting a camper trailer so I'll certainly fit one before I do a lot of towing.

I have the same year, tyres and transmission as well and agree.
I do a lot of soft sand driving and have it stuck on dunes and beaches quite often.
The difference is I have added an additional transmission cooler.
Also, I have the added advantage of inspecting my transmission as I do my own servicing. This allows me to check my fluid condition and pan and filter contents. So far it has been perfectly clean, none of the fine black black residue which is telltale of transmission abuse or fault.
I know this won't help now, but it may influence any future decisions you may make to extend your transmission life and relieve you of some concerns.
How many Kms had you done?
