Lubeguard - 2009 Discovery 3

Used at 135k after experiencing the usual shudder, two tubes added on the Land Rover specialist recommendations. Have had NO issues since, I didn't expect a miracle cure but the Dr. Tranny product has worked a treat. Having the additive sold and suggested by a well respected Land Rover specialist, it's worth giving it a go.

Discovery 4, ZF6 HP26

Used at 138k after experiencing the usual shudder. Two tubes added as per recommendation, and have had no issues since. I didn't expect a miracle cure, but the Dr. Tranny product has some good reviews. There are scaremongers out there that will play the benefits down, but having the additive sold and suggested by a well respected transmission specialist, it's worth giving it a go. If nothing else it'll buy some time.
