can a blown out fuse have any effect on the transmission of a car?

Question

i have a 1999 mercury cougar that cut off on me when i was driving on the hwy. come to find out a 20am p fuse in the fuse box in the engine compartment had blown out. my mechanic replaced the 20amp fuse with a 40amp fuse.i test drove the car and now the gear wont shift from 1st to 2nd.the rpm needle goes up, but the mileage needle stays at 0. .should i be looking forward to a transmission replacement? or was switching the amps up the cause of this problem? please understand i didn't experience any transmission problems until this fuse blew out. im not exactly sold on the idea of replacing a smaller fuse amp with a larger fuse amp cause i fear it will catch on fire. i just need some good advice. and just so u know i purchased this car on april 21 2011.

Answer 1

Never increase the amperage of a fuse, It can cause serious damage to your electrical system! If a fuse blows it only blows for one reason and that is an overcurrent condition (a short exist somewhere) Well if you have 0 MPH you are not getting a VSS (vehicle speed sensor) signal! ADDED; Is the check engine light on or is the OD (overdrive) light flashing? NOTE; A common failure on this vehicle is a failed DTR (digital transmission range) sensor it is also fused!

Answer 2

you in all probability burned via some wiring previously the fuse blew. Pull the radio and look on the harness. verify with an ohmmeter or continuity probe to verify if something different than the floor twine is grounded. verify the foremost harness, too. My wager is which you cooked the foremost potential twine coming off the ignition that feeds your radio circuit. must be inner to the radio, too. do no longer put in a greater fuse till you want a fireplace. Take a while and troubleshoot it. while you're at it, placed some insulating tape over the speaker wires to stay away from a recurrence.

Answer 3

well first off doubling the amperage on your fuse shouldn't cause this issue directly, it is also a HUGE no no to do that, whatever is causing this larger amperage draw could be causing the transmission issues, i would highly suggest taking it to a different reputable mechanic and having them find the cause of the short.

Answer 4

Transmission Fuse

Answer 5

This fuse has nothing to do with your transmission..

your mechanic is a retard for not diagnosing the

transmission from checking fluid to shift solenoids etc
