45RFE to 545RFE TRANSMISSION hack to upgrade from 4-Speed to 5-Speed

[@aussietaipan8700]

From Australia, I did the TCM swap with my 45 to 545 and the result was instant. At 100Km/hr the engine revs were 2200 with the 45, with the 545 the revs are now 1780.

[@affordablehealthplans1180]

I wish I would have known all of this before I bought my 99 Limited. No regrets of any kind, but would have done more to it knowing all of this information. Keep the videos coming with all of your explanations. Makes a world of a difference. Thanks again. Wish I could share pics of mine on here. Drove it for over 100K with a bad lifter. bought with 130K and drove from L.A. to Cincinnati, on Route 66 and back through the northern states. Miss it...

[@xc8487]

In my 2002 KJ, I swapped in the 545rfe TCM from a 2001 WJ. I noticed an improved shift pattern and a 200 rpm drop in top gear. It seems to hold gears more often when accelerating or under load, allowing you to make full use of the torque without constantly downshifting. I recently added a Michigan Motorsports line pressure booster, $18 and 1min install. It now has quicker shifts and feels the way it should have come from the factory.

[@motersickel]

Isn't that line booster a 1.5K resistor?..

Found one and installed it today on my 2000 WJ! 2K RPM at 70MPH is NICE! I used the Build Sheet info website to verify the Jeep at the junkyard came with a 545RFE stock. Got there and discovered someone had already pulled it and left it and the mounting bracket (with the screws) sitting on the driver's seat. Talk about cake walk, I brought tools for nothing lol!

[@sjhotz]

Follow up, i'm noticing rough shifting into 2nd (both up and down) since the TCM swap, wasn't doing that with old TCM, gonna swap back tomorrow to test. Could that indicate a bad 545RFE TCM?

[@jimpickens9219]

Yes! The Blue Dragon (2001 Limited) has the 545RFE! I always just figured it was a 45RFE because it has a 45RFE placard on the side of the transmission case. Thanks for the build sheet tip Doug! Lovin the channel. Thank you guys for representing the WJ community!

[@thedramlin5685]

Thank you so much. A while ago I had the jeep worked on and after that it didn't change the same way it used to and never really got the same fuel consumption that I had previously. I heard along the grape vine that a mechanic working for this business had improved his mates jeep with parts from other vehicles (namely mine). Made complaints and never was able to prove anything. I now have a spare jeep to pull apart and will use your information to see if this part had been swapped out. Awesome.

Wow! Electronically different, Amazing!!! Yea man, Jeeps are muddy Indeed! I feel like Jeep has always been inconsistent with their changes.

[@DEInTheGarage]

Hey bud. Most Jeep models have a two letter distinction. The Grand Cherokee I have (99=04) which came with the 4.7L is known as a "WJ". Long story short, it does not apply to you if you aren't in a Jeep. In your dodge all you need is the TCM from a truck with the 545 and you are good to go!

I have little over 98,000 miles on the 545rfe in my Dodge Dakota doing 10 hr trips across Texas and it’s been great with only a bad relay fuse.

I have a 2007 RAM with a 545RFE and was wondering why at 65 mph on a flat stretch, the RPM would sometimes be 1.8k RPM and other times be 2.2k RPM. I thought the transmission was slipping but your expanation of the transmission potentially having 8 forward gears was really helpful- thanks!

[@z1robbie]

You may be noticing a difference because you are near a shift point. If you are accecerating you may get a higher rpm than if you go sligly faster (letting it shift to the next gear) then slow. I noticed the same thing on my 02 Dakota. Accelerating to 45 the rpms are higher than if I go 50 then slow to 45. Did the hack, 300 less rpms on the highway. Easy way to tell which TCM you have at highway sleep turn OD off then on, 1 up shifts 45RFE (4SP) 2 up shifts 545RFE. (5SP)

Everything I've been reading so far says I can chunk that transmission right in that truck and leaves the factory TCM and it should function as a four speed just like normal or I could use the TCM from the Jeep and utilize the transmission as a 5-speed....

Yes but having eight forward gears also means that there's a problem with fitting as many clutches in the clutch packs and you end up with 8 shitty gears instead of 4 good solid gears. It never seems to work out well. Unless you can make the transmission large enough to put enough clutch packs in it to make it last. There's always a trade-off.

I'm new to this lifestyle and I really want to get an XJ, lift it and turn it into an overlander. Damn, an XJ in good shape is so hard to find in my area (Mid-Atlantic). What year range do you recommend? As a plan B, I'd buy a WJ if I could not find a decent XJ. Which year range and engine would you recommend? Thanks for your help.

If you are going to daily an XJ as well as lift it, get one from 97-01 after they went to OBD II. They are just easier to work on and a bit more comfortable. People will argue that point, but not having OBDII makes diagnosing an issue on what is now a 20+ year old vehicle a PITA. if you go WJ, they are all good, but they made small changes every year so the closer to 2004 you get the better they are. It is nothing major, just small things they improved from 99-04 which make the 04's absolutely perfect. I have videos on both WJs and XJs which explain some of the good bad and ugly. check them out for more info kzbin.info/www/bejne/g6mYqpaVgLOKi8k kzbin.info/www/bejne/Z6HLgJ2jo9Gqq5Y

@D&E In The Garage. Excellent info and thanks for the input.

My trans is so messed up, you give it gas and the whole vehicle shakes. But it shifts fine at higher speeds. 2000 WJ with the 45RE has 167k and I got it for 1500

Inspect all your universal joints. Chock the wheels. In neutral. Don't get run over. Engine OFF. Then inspect your transmission and engine mounts. Lastly, inspect all your front suspension control arm bushings, track bar bushings, ball joints, and all steering components. Worn components can all feel like a transmission with shifting/ vibration problems. Ask me how I know. 😩

Dose it matter how many miles you have on your WJ?

[@DEInTheGarage]

Nope. it is the same as updating the iOS on your cell phone

[@tvstar650]

Hey Doug is this just for the 4.7 or is it also the 4.0?

[@DEInTheGarage]

Just the 4.7. We are stuck with the 42RE as is unfortunately

[@slantedperspective]

I was watching this while driving at 70 in my 45 rfe and I am exactly 2,000 RPMs doing 70

[@charlesnickell7257]

But does this work with the 4.0

[@brendandonovan9040]

That’s what I’m wondering

[@bumblebflow8584]

I was to understand that with durangos only the 2003 4.7 had the 545.

[@DEInTheGarage]

Nope. everything with the 4.7 after 2002 has the upgraded TCM with the second overdrive.

[@VistaViews]

Yep dodge and Chrysler always throw in whatever is left over in end runs. Seen it over and over.

[@chrisruiz1065]

Do these years apply to a 03 Dodge ram?

[@DEInTheGarage]

Your 03 will have the 545 rfe

[@Stanging84]

Thank you very much for this video.

I did this TCM swap on my 2001 Dodge Dakota 4.7L and it works amazingly well. I got the info from another video made by Tony the Truck Guy who did it on his Dakota. As you mentioned it ONLY works on the 45RFE trannys to convert it to 5spd auto. I bought a used tcm from an 03 Jeep Grand Cherokee with the p/n P56044574AC. Simple install and I am extremely happy I did it. You are right when driving on the freeway with a 4 spd auto, that engine is working overtime at speeds of 65mph or higher. Now I am cruising at 60mph @ 1600rpms instead of 2100rpms. It equates to better mileage on the freeway, does not do much for city driving though but I still love it that improved my gas mileage for freeway driving. Here's the video I watched when I did this, kzbin.info/www/bejne/ZonMmHSubZuNppI.

[@RawTruth420]
