Hi gents,
Recently I've started noticing that the 2nd gear in my Puma is very sticky, only really happens in the morning. But now it's getting so bad that when I tried to go out this morning (at around 10 am), I almost had to park the car down the street as I couldn't get into 2nd. The mech says a few Puma owners have also reported the same. They reckon putting 500-750ml of ATF in the gearbox solves this - what do you guys reckon?

Not a synchro then... Well shouldn't be. It's too young.

Could be one of the detents?
ATF fluid was spec’d for the lt77. Not very good for lubrication, but apparently helps shifting. MT82 is very different, and I would be hesitant to add ATF. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

Thanks.
Mech reckons we do a complete fluid change with something full synth, like Motul or Redline. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged ![]() ![]() Defender Puma Workshop Manual: https://bit.ly/2zZ1en9 Discovery 4 Workshop Manual: https://bit.ly/2zXrtKO Range Rover/Sport L320/L322/L494 Workshop Manual: https://bit.ly/2zc58JQ |

I'm going with Redline MTL MTL® 75W80 GL-4 Gear Oil: http://chemsailoils.co.za/product/mtl-75w80-gl-4-gear-oil/
Not cheap, but will see what it does and report back. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged ![]() ![]() Defender Puma Workshop Manual: https://bit.ly/2zZ1en9 Discovery 4 Workshop Manual: https://bit.ly/2zXrtKO Range Rover/Sport L320/L322/L494 Workshop Manual: https://bit.ly/2zc58JQ |

Ok, Redline's been in for about a week now.
Gearshifts are definitely smoother, but there's still a bit of 'sticky' in that 2nd gear - whether it's 1st to 2nd or 2nd to 3rd/vice versa. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged ![]() ![]() Defender Puma Workshop Manual: https://bit.ly/2zZ1en9 Discovery 4 Workshop Manual: https://bit.ly/2zXrtKO Range Rover/Sport L320/L322/L494 Workshop Manual: https://bit.ly/2zc58JQ |
