Basically, last week, the tensioner on the aux belt failed and I ended up having to get the car recovered home. I wasn't present when it was recovered, I basically got a lift to work, got my dad to drop the keys off and then it got recovered home.

Replaced the Aux belt and got the car running again on Friday. Took it for a run and it didn't feel quite right...Accelerator felt a bit stiff and I just couldn't get to grips with the autobox, I was kicking down too much and the car was lurching etc, but I just assumed that because i'd been driving my dads Rover manual all week, the Auto was taking some getting used to.

I've been using the car all weekend though and its just not right. When pulling out to overtake a car and pressing on the accelerator its flat as a fart with hardly any power. Kicking down and it sometimes just doesn't bother, meaning i've got to take my foot off the accelerator then plant it.

When I plant it though, or on the off chance that it does kick down OK, instead of kicking down say one gear, its kicking right down to 2nd, lurching forward and then working its way back through the gears as quickly as possible back to where it was before meaning that its still flat as a fart 

Sport mode is OK though.

What i'm wondering, is I know the place I used for Recovery use a spec lift. Would this kind of issue be likely to come from them lifting the front end of a RWD Automatic and having the back wheels rolling on the road?!

I should add btw that the car had a full re-conditioned autobox fitted 12k miles ago so it's not a shagged 122k/11yr old box !!

It's driving fine around town, its just on the open road when i'm requiring the power that its causing problems.

At the most it would have been couple of miles through a built up area.

Just seems strange that up until the point I stopped the car (due to lack of PAS & temp gauge rising due to snapped belt) the car drove spot on, now its, excuse the terminology, knackered
