My mechanics found today when the car is on the lift, that the transaxle oil is leaking a little. I can see the fresh oil there (not dipping though). He said to open the transaxle and change the gaskets probably will cost $300.
View 5 RepliesI have an 08 Prius it has done 190,000 miles last week it suddenly started shaking from what felt like the transaxle. The car still drove and seem to shake a lot worse when it was in park or reverse it definitely felt like it was a bearing or something mechanical broken in the trans unit. After a bit of research I decided to remove the trans, strip it down and have a look convinced that I would find fragments of bearing or something blatantly wrong. Yesterday I removed the unit (nothing to be scared of, dead easy really) and today I have stripped the transaxle down (after viewing a very useful youtube video) much to my disappointment I cannot see anything wrong I am now thinking I was a bit too hasty and maybe it could be something else.
View 16 RepliesMy 2004 Prius Transaxle overheats and causes a warning on the dash. When I checked the fluid level I found pink foam in the resevior. Do I need to replace the fluid or bleed the system. Also the AC shuts down when this condition occurs.
View 11 RepliesI seem to have gotten a hum coming from the front end when I reach 40mph & higher. Todate, I have not gotten any warning lights, red trinagle etc, but wanted to see if maybe there were some codes thrown.
Lastnight, I put the front on jack stands & had my wife put the car in D & step on the gas while I was laying under the car. The noise is coming from the transmission where the axles plugin. My fear is I need a new tranny.....but if its a code related to the hybird system, I might be covered under warranty.
By the way, my Prius is a 06 w/ 108xxx miles. I changed the CVT fluid around 70xxx miles.
Car was deemed a total loss. I didn't think the damage was too bad and one of my friends at a bodyshop told me to go ahead and do a car buy back that I can't go wrong with a prius. My mother said $20 gas a week. So I did and gave my mom the difference. The Car drives going forward and in reverse just find. Besides the body damage I got underneath the car and I see a bent tie rod end and maybe a lower control arm. The thing is when I hop inside to move the car I notice the car reads transaxle disengaged and battery system won't charge in neutral.
View 19 RepliesI have a 2010 Prius and need to change the Transaxle fluid. I have the Haynes repair manual, but it only shows the drain and fill plugs for the Gen II. I have found what looks like the drain plugs but am not sure of it. Fill appears to be right next to the CV axle and the drain is straight down from the CV axle. Are these the correct fill and drain plugs?
Also, this transaxle seems to have a whine to it. Whines only at kind of a neutral throttle. Throttle pressure or backing off on the throttle reduces the whine. Is this normal or what?
My 07 Prius is leaking transaxel fluid into the inverter cooling system. Transaxel fluid is sweating through the inverter coolant hoses. Before my taking ownership of this vehicle, it had previously been in a front end collision (that’s a whole other story). Anyhow – if I replace the radiator, should that take care of this problem? Are there any other ways these two cooling fluids could become cross contaminated?
View 16 RepliesRecently replaced the transaxle fluid on my 2007 Prius with 47,000 miles. This was the first time the transaxle fluid has been changed in the vehicle. After removing the drain plug I noticed a substantial amount of a thick, grease type substance on the bottom of the plug. When they have change the transaxle fluid on their vehicles? I found minimal metal shavings on the plug, but was concerned on the thick sludge/grease substance on the bottom of the plug. The ATF fluid that I drained was very dark. Definitely not close to the red color of new ATF WS fluid.
View 19 RepliesI have replaced a bad module in the HV battery and balanced it. Inverter coolant pump has been checked and inverter coolant has been replaced. Engine coolant has been drained and refilled. (Both coolant jobs followed Haynes manual guide including bleeder valves.) Transaxle fluid is full.
After each step of troubleshooting I have done a test-drive. Warnings come on consistently within 2-2.5 miles, day or night. I do not have a scan tool, but I do have the trouble codes from Toyota (all prior to my repairs). Is it possible that a bad ECT sensor could trigger all of this?? Is there something else I can check?
I had whining from the engine compartment when I am coasting and accelerating, much noiser than in the past. I had been getting a C1310 code along with C1253 , C1241 and C1300, but I changed out the Anti Skid ECU and these went away. However I still get the red triangle of death VSC and ABS lights on after driving on the highway for about 10 minutes at speeds over 65. So I then got P0A2B 250 codes, Drive motor A temperature sensor. After it rested a while and I restarted the car, all but the red triangle would go out. After two more starts the Red triangle went away too. This happened for a few weeks, until one day after a trip, the car just stopped. Would not start at all, no ready light went on. Testing gave me a P0AA6 526 code, Hybrid Battery Voltage System Isolation Fault. Now I know the 526 could be multiple faults but with the whining and the P0A2B, I am thinking the transaxle is the smoking gun.
View 14 RepliesI have a 2005 Prius with 110,000 mi. Sometimes when I accelerate the ICE (gas engine) simply spins (as if the clutch was slipping in a convention car) and there is little acceleration and the gas engine doesn't shut off when coasting or braking as it always has in the past. The battery screen shows it is not charging when this happens and is at 1 bar (purple). then sometimes the hybrid battery gauge will go from 1 bar to fully charged (green) in under a minute or 2 and then show discharging just as fast which isn't possible. It goes away after a restart sometimes but then happens again soon. Is it the TP sensor, Hybrid battery computer or ? I have gotten all kinds of codes including P0a93, P0a80, P1400, P040a.
View 14 RepliesI have a 2005, I purchased new in 2005. I now have around 120,000 miles and have had no problems - just oil changes and new tires.
I was driving on the interstate in MS and all of a sudden all these lights come on on my dash including the triangle that means take it to your dealer immediately. The car sounded funny acted funny and accelerated funny. I was closer to home so I came home and called the dealer. They said to drive it in but if it started acting up to pull over and they would come get me.
When I cranked it, it sounded like I was pushing the accelerator but I wasn't so I cut it off then cranked it again. I drove it very slowly cause it was acting weird.
I drove it home to discuss it with my husband and to do some on-line research here. So 2 - 3 weeks later my husband decides to look at it and by now the little battery is dead - it is the original battery too -btw. So I bought a new toyota battery (the little one). My husband hooked it up to see if the car would crank. It did but all the lights on the dash lite up again including a couple new ones!
Long story, but I bought a 2007 Prius with 73K miles on it. Now I'm at 93K miles, and I think it may be more jerky than when I got it when I shift the tranny into "brake" mode.
I don't know if the fluid has ever been changed on it, and I intend to change it very soon now. Am I in a pickle? Or should this transmission be fine if the fluid hasn't been changed for 93K miles?
I came across this site that seems to implicate very common issues with failures in gen 2 : Transmission Slipping ! | Hybrid Cars
With people experiencing lack of power and "slipping" sensation or tranny going from drive to neutral.
I thought there were common issues with gen 1 motors burning up inside transaxle, but I thought gen 2 was much improved with only rare failures. Yes, I did read both sticky threads giving very detailed accounts how to replace them.
Took my 2007 Prius into the local Valvoline where they said they could drain and refill the transaxle fluid. The guy undid the bolt a bit and said he got fluid mixed with water, no odor. He closed it back up and refused to further service it due to liability. I think he opened the drain for the inverter coolant, not the transaxle fluid drain plug. When I called them back, the guy said he used a standard wrench to remove the bolt. NOT a 10mm hex key.
I drove the car home about 3 miles, but now I'm concerned about possible damage to the engine, how much fluid he let out, but the inverter coolant tank appears full.
I just acquired a 2006 Prius with 96000 miles. My local service station said he did not want to change the transaxle fluid. He said he had changed it for someone and the car stopped working. My son the mechanical engineer said there is a risk that changing the fluid can dislodge particles that were not a problem and cause a problem. I don't drive many miles -maybe 3000 per year, so car will be 19 years old by the time I get over 130,000 miles. So I am not looking for the transaxle to last 200,000 miles or so.
View 14 RepliesLooking for a diagram for the front transaxle on a f350 4x4?
View 4 RepliesI have a 2007 Prius 3 Touring Edition. I purchased it new in Dec. 2006. I have had NO issues with my favorite car of all time, and currently have 90,600 miles. I have noticed a high pitch for a long time coming from the transaxle during acceleration. The pitch is only present when MG1 or MG2 is engaged. The pitch stops in stealth mode. My finance also has a 2007 Prius, and her's does not make the noise or whine when I drive her vehicle.
I have changed the transaxle fluid at 65,000 miles, but I did not see the plug when it was changed so I don't know how much, if any, shavings were stuck to the magnetic bolt. If you are wondering, yes, the high pitched noise was present before the fluid change. Also, as I accelerate and increase speed, the noise pitch increases.
Is my transaxle displaying a tell-tale sign of imminent failure?
I just got a 2006 Prius and I brought to Toyota dealer to do a regular oil change. After that, been told that I'll need a Inverter Coolant and Transaxle fluid change in next maintenance point.
This prius already has 111,000 mile now.
I have an 06 Prius that I got needing a transmission. I picked up a used transmission from the junkyard, and I started working on it today, but I am having a problem. The big orange cables that go from the inverter to the transaxle have been cut. So I need to swap over my good cables (from the bad transmission) over to the new transmission. I need to know how the cables are removed/installed from the transaxle side. They don't seem to want to pull out.
