Depends, a repo stays on credit for 7 years, and a bankruptcy stays for 11 years, after you have paid off a debt and they have received payment it should be taken of immediately, but you may want to get a free credit report and check and if it is still there call them and ask them about it.
The realistic time frame for you ranges from 30 days to 90 days. In some cases, paying off your loan can take a bit longer than 90 days, though it is not supposed to. A good rule of thumb an a car loan pay-off is 45 days. You credit score on all three credit reports will reflect the loan payoff eventually, though Experian might come in at 30 days and TransUnion at 45 days. Might be a good idea to sign up for the three-in-one credit report when your loan is paid off.
