Mark Levinson Sub - $750

Both driver side door lock actuators - $900
Mark Levinson Nav Unit - $2000
All replaced with OEM parts and all done at Lexus. Fortunately, I bought the extended warranty when I bought the car. The dealership has told me many times the company I have is the best they've ever seen. Best of luck to you.

It appears I have made history as possibly the third person to have a ISF transmission go (2008, 80k). I'm a engineer so I understand that this might just be a overlooked defect and there is always a percentage of parts that will just not meet the standards but still get by QC but it still makes me salty since I have always preached about the reliability of the ISF and Lexus in general. Now I can only hang my head in shame around my BMW friends

Summary of the issue:
Earlier this week I was pulling into a parking spot, next to a M3 no less, and I go back to up and it feels like I'm the parking brake is on in reverse. The car vibrates and it moves backwards but the whole time is jerking and feels like it's mechanically slipping. I get out of the car and nothing is blocking my way and no fluids are spewing out. I drive forward and everything is normal. So I decide to test it. I have all forward gears and everything is normal, pop it in reverse and the car is vibrating and lurching like a ****box. I take it to Roswell Nalley Lexus near Atlanta (because those guys have a good rep and know our F's). I get a call back the next day and the transmission is the culprit, All fluids where fine (level/color), my guy at the dealer tells me that he has never seen this before and says I just have a fluke transmission. The crazy part is, that of all things to go, it's reverse, so maybe it is just a fluke. The good news is I have a extended warranty that came with the car when I bought it, the bad news is it's a 3rd party warranty, so i'm expecting to get jerked around a bit and they will probably honor my repair with pennies on the dollar. Anyone in the community got a spare transmission they want to unload, worse case? I might need some help here guys.

That is wise to replace the transmission fluid every 60k miles even though lexus recommended not too. I talked to several guys that did that here in the forum tough luck to you , hopefully the 3rd party paying for it.

I drove it from Sacramento to Socal and made only one stop for fuel. Never used reverse (because it didn't work). Going up the down the 5 freeway into LA, i downshifted a few gears to go up the hill easier, eventually, my transmission stopped shifting into 7th and 8th.



87k miles is when I had the transmission replaced. Lexus paid for half the cost of a remanufactured transmission, which was like $3000 something and then I paid for labor, which was $1000 something.

1) A warrantied used transmission with 40K on it (not sure the year, I'm trying to get that info)- I pay ONLY a $100 deductible!

2) A warrantied Lexus refurbished transmission- I pay $2K

Both transmissions are warrantied for another 25K or 2 years through the warranty service contract.

I think I'm going with option 1.

I asked if they would reimburse me if I supply my own transmission and they said no unfortunately.

Thanks guys for all the support through this so far! hopefully the repair goes smoothly. Thanks to all those who where finding sources for a transmission or offering to sell me one. I hope this doesn't happen to any more of us, I already miss my F and I was supposed to send my ECU today

I want to keep the busted trans for investigation purposes but i'm not sure if I need to send back the core, I'm figuring I don't since the transmission seller is not a re-builder. Unless Lexus wants it for investigation purposes.
