2008 Prius w/151k miles,Needs new transmission & has 2 dead cells of hybrid battery. What to do?

it depends on your financial situation. if you can afford it, get what you can for it and move on.

if not, repair it, understanding that the battery, tranny (and other expensive things) will fail again.

 

What are the actual codes that came up? Your Prius does not have a transmission as you know it, don't trust those guys. Why don't you get the codes read at the Toyota dealer in Eureka?

 

I'd say $3k is suspiciously low for a proper repair of the issues you're describing, assuming they have been accurately diagnosed. (This is a big assumption.)

I'd be looking to get out & start over.

 

I agree that codes would be of lot more help. Transmission (transaxle) in this car is extremely reliable. But that is the reason transmissions from junk yard are quite cheap. I had an accident which cracked transmission housing and thus needed to be changed. Transaxle and cross member from junk yard cost me $2500 installed. So 3000$ may be a reasonable amount if it is junk yard parts. But codes may point to whether it is really needed.

It worked out to be a good decision for me since I have since added 210K Miles in 8 years.

 

I just replaced the traction battery in my wife's 2008 with 160000 miles. Cost for new cells was $800.00. I did the swap out myself. On my 297000 mile 06 Prius I did an engine/transmission swap for $650. Unfortunately the car was totaled 400 miles later. Btw, I'm now driving a 2007 Prius Touring model, courtesy of the driver's insurance company, and kept my wrecked Prius for parts. You can keep them running.

 

Having the actual DTCs and associated INFs would be helpful in determining a course of action.

Which part of the metroplex are you near, as I might be up in that area in the near future.

 

if you can't afford to keep putting money into it, can you afford something newer?
