Okay guys I have an 04 4x4 with the 5.7, for about 5 months now my truck sometime does not go right into reverse when I shift it. I will give it a little gas and once the RPMs get a little higher then it will start moving in reverse. Within the past month or two I've noticed my truck is shifting harder between 1st/2nd and almost feels like a transmission that is slipping a little.

I was wondering if you guys know what my problem could be? I did a little research and maybe its my Governor Pressure Sensor screen is clogged?

Would I just need to drop the pan and clean the screen off? Or should I replace the sensor/solenoid? I called the dealer and they don't sell them individually, only the whole "Shift Pack" which is $340


Any suggestions would be greatly appreciated.


Thanks,
Spencer

 

When was the fluid changed last? You can't clean the screen. It has filter media inside and cannot be cleaned. You would need to change it out completely.
I made a How-to-flush in the FAQ section. You can follow that and see if your trans shifts better after.
Also, there's a return filter which can cause slow engagement due to leaky drainback valve.
Here's the complete WIX kit:

You'll need like 20qts of ATF+4 to do a complete flush. The system hold 17 I believe.

Here's the flush procedure:

mine was doing the same then one day last summer it would not back up at all took it to tranny shop they found that the reverse piston had broken so I had it rebuilt it wasn't 3 months later it did it again fixed under warranty and it was a billet piston sounds like its a common issue my tranny issues are covered for as long as I own the truck

 

And you had a 545rfe trans? I havent heard a lot of problems about the reverse piston so it's not exactly common.

 

yes I believe that's the trans 02 1500 4x4 quad 5.9 its been about 12k since they replaced the last one I am glad I bought the unlimited lifetime warranty now I don't care if it goes out again

 

2002 5.9L I believe still used the 454rfe(4spd) but I dont know if there were any differences with the valve bodies?

 

It has been a while since my tranny fluid has been changed (around 50k miles), I was planning on changing it when I swap the filter and whatever part needed to get my transmission shifting right again

Can you purchase just the individual sensor or do I have to replace the entire shift pack?



Do you think that a filter and fluid change alone could be the solution? I would just hate to drop the pan and swap the filter and put new fluid and then have to pull the pan off again to swap a sensor or shift pack. It's pretty cold here and I don't have a garage to work in right now

anyone?

 

The TRS solenoid pack assembly is one unit. I had to replace mine this fall, it was fairly easy. In my case though, and in most that I've read you get an engine trouble code when that's the issue.
I would go with the complete DIY Transmission Flush that dirtydog did a write-up on before throwing money at that part.
How many miles on your truck?

 

I've got 95k miles on my truck, I will flush the tranny this week and let you know how that goes


Thanks,
Spencer
