Transmission clunk into reverse gone after full trickle charge
Okay, so my 2003 Disco II had trouble starting the other night. Fortunately I was home. Battery was low from all the short trips I've taken. Gave the pretty new 800 CCA Interstate Battery (sticker on it says 2/16) a 36 hour slow 2 amp trickle charge. Re-installed the battery and the car started right up immediately.
Now here's the bonus. Ever since I got the car 4 months ago, I would clunk into reverse on a cold start. Guess what? The clunk is now completely gone. Smooth shifts all the way around. Pretty cool for a simple full battery re-charge. Just thought I would pass the tip around.
So far, I'm more than pleased with my $2,300 Disco II with 85k. It's a pleasure to drive and just found out it came with a pretty new battery too.

It's a pretty serious "clunk" on the D2. One of the ECU re-mapping companies states that with their programming the clunk is almost eliminated. Maybe one of these days I will send mine off. I usually get anxious when I have to shift from P to R but I have recently found that if I shift into Reverse immediately after the engine starts then the "clunk" is much lighter/softer..by a LOT.

The clunk is worse in the colder months of the year as the ATF thickens up. Re-programming won't eliminate the transmission backlash in the system only new components can do that ................ if you're lucky

To reduce the clunk try putting it in neutral first and then reverse.

I have tried going from Neutral and still harsh enough to make me flinch. You could be wrong about that. There is no "backlash" that I'm aware of. The fuel isn't being cut at the shift so eventually the splines wear down on the coupling of tranny output to transfer input. If the fuel is cut the engagement would be much softer and then the splines wouldn't be wearing down at the coupling. that's what I think about it, anyway. I'm sure that's what they do on the ECU...program the engine to cut fuel on the shift from Park to Reverse, right?
