Legnum Shudder In Lo Revs

My wife has a 1998 ST-GDI 1800cc Automatic legnum and it from time to time tends to shudder in low revs when in 3rd gear and fourth..not majorly, but enough to be noticeable. Does has anyone else experienced this and does anyone know why and how to fix it???

appreciate any advise..

Have a look at clubvr4.co.uk and search on shudder. There are a couple of possible problems - worn parts or a faulty lock-up mechanism. Good luck.

Cheers for that..Will look into it.

I had the same problem a while back, turned out that it was worn transmission and engine mounts

jbo is it on a light throttle like when your driving at a constant speed revs between 2500rmp to 3500rpm

I have a silmilar issue. aout transmission. car starts shuddering when revs drop off in third or fourth. Highly annoying

Sometimes this issue can be sorted with a good transmission flush.

Don't forget that the GDi Legnum requires high-octane low-sulphur fuel for maximum performance and engine protection.

Hey all , this stuff works a treat on the GDI engine !!!
