I have a 2002 Nissan Xterra. Couple days ago, daughter came

Customer Question

Customer: Good morning. I have a 2002 Nissan Xterra. Couple days ago, daughter came home indicating that vehicle was accelerating badly, transmission was slipping. Rand scanner and cope for bad TPS came up. Switched out w new one. Adjusted idle now runs and accelerates as it should, but transmission continues to slip after trying to go into 3erd sometimes 4th gear. Problem related to TPS or separate?
JA: Thanks. Can you give me any more details about your issue?
Customer: No leaks with transmission fluid, slipping didn't start occurring until this past Friday. Replaced TPS sensor following morning. Ran test drive, slipping cleared up but now it is back. Does the transmission go into what I've read is a safe mode and does that have to be cleared by a technician?
JA: OK got it. Last thing – JustAnswer charges a fee (generally around $20) to post your type of question to Nissan Experts (you only pay if satisfied). There are a couple customers ahead of you. We can help you for less if you're not in a rush. Are you willing to wait a bit?
Customer: Yes of course
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

I am sorry that you have not been helped yet. I just came online and saw your question

The slippage is a separate issue. You need to check fluid level, fluid color and smell. If dark or burnt smelling, you need to change the fluid and filter and check for metal shavings in the old fluid. If found, you are likely looking at worn bands and clutches and will need to rebuild. You can confirm by taking for a test drive with new fluid and filter in it. If still slipping, time for a rebuild, and if not, it was just worn fluid and dirty filter
