I have done a chip by sa chip tuning about 3moths back and my car starts missing when it idles and it is like when I stop and go
It does not go immediately into gear,can it because of the chip or what,thanks

I don't know who sa tuning is, nevertheless, I doubt that's your problem.
Do you have any codes (CEL)?
You may have a coil pack that's gone bad.

As for your tranny, it's an 02 which is about one little step better than an 01 tranny... which is AWFUL.
You need to have someone (a Volvo mechanic) check it out
What is the condition of your tranny fluid?
Has it been changed?
What is your current mileage?
Etc
Etc
You need to post all this before anyone can give you ideas where to look

You probably have water in a plug.
Chage your plugs

Okay thanks,what do you thinnk is wrong with my gearbox,it change nice and smooth but when I want stop or brake suddenly and put immediately
Power it is like it slams into gear but when I put power very slowly iys fine its like it doesn't know what gear it supose to gear down,its automatic
Last when I done the chip it strucled to get gear and I took it to volvo and they drain the oil and load new softwear for the gearbox and ita finne now
Its only when I put it in reverse that it clicks hard and when I stop and go and put the pedal down it search for a gear I also putted prolong and it doesn't help

If you already flushed the transmission recently and it's starting again, your transmission is probably going south, (broken)!
Before you continue modding with stuff you really seem to know nothing about, AND will make the tranny (and other parts worse, (as did your chip with more power) FIX THE TRANSMISSION, and that will probably be your budget for the next two years!

There is a cause and effect situation when you start trying to make more hp without your car being (1) at stage 0 (look that up), and (2), NOT knowing what you're doing.
Mechanical parts that seemed to be OK are now over stressed and failing
