The 545rfe used behind the 4.7l v8 does have two second gears. The extra second gear is only used as a passing gear.
The transmission defaults to second gear when it detects a malfunction.The transmission defaults to second gear when it detects a malfunction.
I just fixed a 2002 Dodge Neon that would not shift up it was stuck in low gear replaced TCM now trans is working fine
With a special puller.
i kno how 2 check your oil ;D
If it will not go into gear you have probably missinstalled one of the filters.
Of course.... the differential / transaxle uses a Mopar 75 - 90W Hypoid Gear oil
Trouble code p0731 means: A/T Additional Gear Ratio Error In First Gear
This is because the transmission is in the limp home mode because of a speed sensor failure.
If the front is 3.55, then the rear needs to be 3.55
75w90 synthetic gear oil.
The transmission computer defaults to second gear when it detects a malfunction and sets a code. You need to have the TCM checked for codes to know possible causes.
