TOYOTA RAV4 U140F Transmission 2000- up

Complaint:
Bind up/ flair up/ chatter in 3rd gear

Cause:
As we see a lot of these transmissions come through our shop through our affiliation and partnership with Toyota, we are seeing a trend of similar complaints.
The above complaint can be caused by the transmissions E.C.U.

Correction:
Beware !! As it may seem that the transmission is at fault given the above symptoms, don’t overlook the E.CU. (located behind the glove box).

If an attempt is made to replace/ repair the transmission without examining the E.C.U chances are that you may hurt you new auto once installed. Then you will be up for a 2nd transmission and the E.C.U on top. Ouch!

Result:
Get the trans / E.C.U diagnosed correctly by your local trans guy or Toyota dealer before making any decisions.
