[Painter16]

Just been out in sl 10 mins from home when got suddenly lost power put me foot down just revved put built up speed very slowly so pulled over put into N then into drive then had no gears at all so turned off car then turned back on and everything back to normal. No warning lights came on ,so have not got a clue any ideas peps thanks

Could be the speed sensor on the electroplate is failing. You need the gearbox codes read to be certain. Have you had the ATF changed lately? Its due every 37k miles.

Thanks for ya reply ,sorry to sound dumb but not sure what ATF stands for,just been out again and no probs at all,I've only done 8000 miles since I've had the car,the car as nearly 70.000 on it,had the car 15 months,

Sorry yes I am dumb ,no I haven't had the ATF changed since I've had the car,I'm having a b service done in June same time as mot due,it's saying on dash that it's 30 days over but I haven't done the miles since the last service

What kind of history did the car have before you got it?
I'm also wondering ATF fluid for a start but you need fault codes checking asap- worth bringing your B service forward and add ATF change?
I'm wondering if it's ever been done....

My SL500 service book diesn't mention ATF changes at all! Had mine done a month ago anyway as a precaution.

This was really bugging me so I finished work early took it over to me inde,about 12 miles away drove perfect,told him and said same as you guys booked in now end next week for b service and will put on star check whatever and I'm getting ATF changed anyway, looked in service book it as been changed at 39000 with a b service at merc in Chelsea,car as done just under 70000.

Great- and good to hear the ATF was changed more or less in line! Good luck

Wise!

My indie said the drained ATF looked pretty good but as i couldn't find any record of the ATF ever being changed i figured better safe than sorry.

Well sl went in for b service yesterday ,I've had no more probs with it going into limp mode since Put this on here,the a.t.f was changed at 40000miles according to service book ,Chelsea merc ,car as just under 70000 on clock now,my inde checked it said its perfectly fine no need to change it for another 10000 miles so car was put on star he does this anyway part of b service found out it was a air pipe had come off sucking in air hence limp mode,anyway put back on and fine again air con was little low he sorted that gave it a valet inside out side ,every think good again ,
So thanks Marc at amcs merc ,won't take me car any were else really knows his stuff ,think. good price as well £388 with vat ,
