Occasional minor slipping between 2 and

[Alex Walker]

Like the title says, I'm having minor slipping between 2nd and 3rd gear on my 97 Tiptronic. No CELs yet, but I was wondering if there is anything I can do about it myself, or if I should just take it in for service. If the latter, what can I expect to have done and how much $$ roughly.

Thanks in advance.
