Restored faulty transmission to as new for 50k miles
I had a tuned Mercedes c250 Td sport automatic. 260 hp (standard power 150hp). It started to not shift into 5th when cold, then started to fail to go into 4th too despite having had a recent service. Mileage was 120k at the time.
I drained 700ml transmission fluid, added a bottle and it behaved perfectly for 30k miles when it started doing the same thing again albeit intermittently.
I changed the ATF, filter and added another bottle of this stuff and drove it fault free for another 15k miles at which point I crashed the car.
This stuff saved me a lot of work. Transmission had no fault codes so it might have been some issue in the valve body which this stuff fixed semi permanently. Excellent stuff. I now use it preventatively on all my Mercedes 722.6 gearboxes.
Picked up one of these for a suspension rebuild I'm doing on an old Merc.
I already have a Halfords pro 3/8 torque wrench for more sensitive jobs but didn't fancy spending £75 on a 1/2" torque wrench for general work like suspension.
This wrench comes in a case (it's essential to keep a torque wrench clean and safe to maintain accuracy) and the wrench itself feels decent quality.
I linked it up to my much more expensive Halfords pro torque wrench and torqued them against each other at 30 and 50nm.
What I found was that they are calibrated within about 3nm of eachother. Impressive! I'm confident it's going to do the job brilliantly.
