Thumbs up, Awesome! I received the booster kit today. Installed it on my 2012 Ram 1500. Did a hard reset by connecting both battery cables together for a minute or two. Have 50 miles on it right now, so far it's shifting great. I'm a happy customer, thanks.
@@sonnax Question, my co-worker asked me what's the difference with this kit or just riding with the tow/haul button on and I really couldn't answer him, could you help me give him a good answer? Thanks
@@wilsolo1986 Tow/haul mode changes shift patterns, and can sometimes block out the top gears. For instance, in a 6-speed it might keep you in gears 1-5. Our line booster does not alter shift points, but increases pressure for a more positive shift feel. Hope that helps, thanks!
One of the issues I’m told with the 66RFE is low line pressure to 5th and 6th gears. Your kit should fix that issue if I understand what you just said. Excellent video by the way.
Thanks for the feedback! The RFE-LB1 will raise line pressure progressively from about 10 psi at lower pressure ranges to 25 psi increase at higher pressure ranges. This will provide improved clutch holding capacity in 5th and 6th gears. If you have any other questions, our product support team would be happy to help you.

03 ram 1500 with 545 RFE here. Ordered your part. My problem is the tranny shifts into low gears too early and very soft shifts. Just had dodge reflash the trans computer.

I have a general question about a valve body that I can't find an answer to. If you'd be so kind to give me advice I would be grateful. It's regarding a completely different automatic transmission, a SJ6A-EL from a 2017 Mazda MX-5. I saw a video of a mechanic adjusting the "pressure control valve" (boost valve?) without even taking the valve body out. He just used a flathead screwdriver to easily adjust this valve to a higher setting and claimed that this boosts the pressure a little and will improve shifting response. This was on an unmodified valve body with no "shift kit" installed. So My Question is: is it safe for me to adjust this valve to a higher setting or should I leave it alone? Would it really slightly improve shifting even without a full shift kit in the valve body? Keeping in mind that my car is stock, 80k miles and I don't abuse it. It shifts fine the way it is (a little too smooth for my taste) but if I could improve it a little without putting extra wear and tear on the transmission with this simple adjustment that would be great. Thank you for any suggestions on this.

Great video information! I have a 2011 Chrysler Town & Country. with the 62TE trans. It just started slipping from 2nd, to third. I changed the filter and fluid. Cleared codes. Drove it around the block gently. It started slipping a little worse with a slight whine. I see a new check engine light. It read P0869. This motor/trans does not have a TCM, just a ECM. This code shows line pressure high. Low fluid, ECM, or wiring issues. Fluid is Ok, would changing the solenoid pack, and Tcc solenoid possibly help? The car has never had any trans issues, I have changed the fluid and filter every 60K. Any recommendations?

Yes, they do. There are several options available for adapters (here is a link to one Transtar sells: www.transtar1.com/products/transmission-tools-and-equipment/featured-products/Line-Pressure-Adapter-Tool). Just remove the line pressure sensor and install it in the adapter. Install the adapter in the case and reconnect line pressure sensor. Now you can verify actual line pressure and compare it to what the scan tool is reading.
My 545RFE won’t shift into higher gears (my max speed is like 25mph at ~3000rpm), even when I auto-stick shift to 3rd and the instrument cluster says it’s in 3rd, but really isn’t. Will this higher line pressure trick potentially get my Jeep to shift? Either way, cool idea and great video!

This is similar to a "boost fooler" for the turbo, with no actual hard parts that are made for the tuned power. It simply tries to trick the system and from personal experience that is never a good thing because when the system thinks it's doing one thing and it's actually doing something else, that's when things get angry and hate life. If you electronically trick these trucks they hate life. If you want better line pressure spend this money on an actual kit for the valve body. It's not half as scary as it sounds to work on at all. And if your scared to work on your valve body or any part of the transmission just go to Amazon and grab the "ATSG 48re manual" book and it walks you through every single part and how it works and how you take it apart and put it together. A 5year old could rebuild a 47, or 48re with the "ATSG 47, 48RE TRANSMISSION MANUAL BOOK" firepunk also offers the atsg manual on their website and offers phone tech support from a real tech who works strictly on our dodge ram trucks and their transmissions. Not hating on this company at all but these trucks don't like tuning of any sort without hard parts to back up the tuning and your transmission will thank you later 😊
Thank you for participating in the discussion about raising pressure RFE’s and 68RFE. The RFE’s are a very different animal than the 48RE, and transmission line pressure control is achieved by completely different methods. Our experience has shown the best outcomes for vehicles is achieved without changing the OEM transmission tuning. Even the valve body kits that raise pressure do so by "tricking" the computer control. The Sonnax RFE-LB1 electronic booster kit is the original "tuneless" method for raising transmission line pressure in these sophisticated, closed-loop pressure control systems and works as intended.
2011 ram 5 speed with 152000 miles on trans,no problems but never have service trans. Normally I change my own filter and fluid on trans every 50-60 I but been so busy with work oops life happens. Would you recommend doing this or could I damage trans with not having serviced trans?

This is similar to a "boost fooler" for the turbo, with no actual hard parts that are made for the tuned power. It simply tries to trick the system and from personal experience that is never a good thing because when the system thinks it's doing one thing and it's actually doing something else, that's when things get angry and hate life. If you electronically trick these trucks they hate life. If you want better line pressure spend this money on an actual kit for the valve body. It's not half as scary as it sounds to work on at all. And if your scared to work on your valve body or any part of the transmission just go to Amazon and grab the "ATSG 48re manual" book and it walks you through every single part and how it works and how you take it apart and put it together. A 5year old could rebuild a 47, or 48re with the "ATSG 47, 48RE TRANSMISSION MANUAL BOOK" firepunk also offers the atsg manual on their website and offers phone tech support from a real tech who works strictly on our dodge ram trucks and their transmissions. Not hating on this company at all but these trucks don't like tuning of any sort without hard parts to back up the tuning and your transmission will thank you later 😊
Thank you for participating in the discussion about raising pressure RFE’s and 68RFE.
The RFE’s are a very different animal than the 48RE, and transmission line pressure control is achieved by completely different methods. Our experience has shown the best outcomes for vehicles is achieved without changing the OEM transmission tuning. Even the valve body kits that raise pressure do so by "tricking" the computer control. The Sonnax RFE-LB1 electronic booster kit is the original "tuneless" method for raising transmission line pressure in these sophisticated, closed-loop pressure control systems and works as intended.
2011 ram 5 speed with 152000 miles on trans,no problems but never have service trans. Normally I change my own filter and fluid on trans every 50-60 I but been so busy with work oops life happens. Would you recommend doing this or could I damage trans with not having serviced trans?
