In transits to your Natal or Progressed chart, he will lend his influence to those areas affected by the resident House.  For example, while in transit in your 2nd House of income and possessions you could get a financial windfall or in the 10th House you could get a promotion. 

In aspect with other planets, either natally or by transit, the results will be further colored by the other planets involved.  If the Sun, expect attention to be drawn to you or your accomplishments; the Moon, emotional issues; Mercury, communications will be expanded; Venus, comfort, beauty and affection; Mars, increased energy; Saturn, bureaucratic issues, responsibility or reputation; Uranus, unexpected events; Neptune, inspiration, intuition, fantasy; Pluto, introspections or obsessions. 

Again, house placements will further indicate which area of your life will be affected.  For example, in aspect to Venus with one or the other in the 7th House of relationships should bode well for your love life.  Naturally the Sign comes into play, also.  An aspect to Saturn in Cancer in the 5th House could indicate a change to a larger residence to accommodate a significant hobby/avocation or possibly the arrival of another child.

When Jupiter goes retrograde it draws attention to any need for reassessment regarding the Jovian issues previously mentioned, e.g., long distance travel, academia and legal matters and often focuses on ethics issues.  Are the precepts still valid or is it time for some adjustments? This will start at the global transit level and work down to you as an individual.  By transiting your own Natal or Progressed houses, Jupiter retrograde could stimulate them in the following ways:

1st House:  Is your personal integrity and value system in place?  Do you live by it?

2nd House:  Are your finances and possessions in order?  How important are they?  More so than people?  Are you honest in attaining your income or a snake oil salesman who epitomizes "let the buyer beware?"

3rd House:  Are your current thoughts and decisions in synch with your belief system?  Do you treat your siblings and neighbors with integrity or with less regard than the others in your life?

4th House:  Is your neighborhood and home a true reflection of your deepest desires?  Does it represent you well?  Are you proud or embarrassed to live there?  Are you treating your family properly?

5th House:  Are you keeping to the same standards you teach your kids or are you a "Do as I say, not as I do" type?  How do you behave in romantic relationships?  What about speculations? 

6th House:  Are you honest in your work?  Are you comfortable with your employer, its standards and policies?  Are you a good example who represents your company well?  What about volunteer work?  Do you perform it as diligently as you would if you were getting paid?

7th House:  Are your relationships as they should be?  Are you honest with others and yourself?

8th House:  How self-serving are you when it comes to sex?  Are you self-sufficient in your finances or do you depend on credit cards or exploit friends or family members?  How respectful are you of life?  Do you suck up to older relatives hoping they'll remember you in their will?

9th House:  Legal matters or property disputes could arise.  Will you handle them properly or exploit others?  Did you attain your education honestly or make your way through school by cheating?  Are your beliefs reflected in your actions or are you a hypocrite?  Are your a priori assumptions valid?

10th House:  Are you comfortable with your reputation and community standing?  Do you care how you're viewed by others?  Will you do anything, moral or otherwise, to advance your career?  Is everything on your resume true?

11th House:  Do you exploit others in your work environment or within any of your social circles?  Are your aspirations honorable?  To what lengths will you go to attain your goals?

12th House:  What are your spiritual values?  Who are you at the core?  To you try to undermine those around you to advance your own interests?  Are you deceiving yourself in any way?  Are you a productive member of society or a drone?
