When working properly, the 68RFE and Aisin AS69RC are a great transmission. Unfortunately, though, when things go bad, they go very bad. The 68RFE especially has been plagued with a high failure rate that many attribute to the fact the converter in this transmission never goes into a full lockup, which creates excessive heat, and we all know what heat does to a transmission. Interestingly enough, this easy to install bypass valve delete can keep your transmission temperatures in check in certain environments, potentially saving you a heap of money.

Another part that can be damaged by the heat allowed to pass through the factory bypass valve is the factory plastic filter coupler. To remedy this, ATS manufactures and includes a billet filter coupler so that the filter has a solid mounting point which won't be compromised by higher temperatores or over-tightening.

HOW IT WORKS: Ram decided to incorporate a transmission cooler bypass valve into the cooling system of the 68RFE and Aisin AS69RC that bypasses the transmission cooler during cold operation. The intent is to force the transmission to warm up faster. The reality is this bypass valve leaks and sticks in the bypass position in almost every case, causing the transmission cooler flow to bypass the trans cooler, essentially eliminating the trans cooler from the circuit. This causes severe damage to the transmission over time because it is not being adequately cooled by the transmission cooler. The ATS cooler block replaces the faulty design, eliminating the bypass valve and ensures 100% of the trans cooler flow is forced through the trans cooler. In every case this substantially reduces transmission temperatures.

IMPORTANT FITMENT NOTES:
  • This product will only work on 68RFE and Aisin AS69RC transmissions.  The AS69RC is found on cab and chassis models, which is different than the ASC69RC, found on the later model High Output Rams. If you are uncertain as to which transmission you have, please reference your build sheet.

Stop Thinking... Buy this part ASAP!!!!!!!
Best modification for Ram 2500 with the 68rfe. Temperature now at 145 compared to 170 degrees unloaded. When towing our 5th wheel camper was the real test because she is now at 167 degrees compared to 210 degrees. Camper loaded is 14038 pounds and is 42 feet long. Truck shifts so much smoother and is so much happier without all the excessive heat. Don't think buy this now. Plus they included billet transmission filter nipple for free with purchase. Thanks so much

Best Mod for my 68RFE so far!
Ideal product for my 6.7L CTD 68RFE! Especially while towing heavy! Average temps unloaded were 165-169*F Loaded 12-15Klbs = 172-196*F Now with the Delete block installed Unloaded 128-135*F Loaded 145-165*F With Schaefer's All-Trans flowing along with the much lower trans temps it's now a Win/Win!

Thank you for the review, and great to hear that such a simple upgrade delivered a massive drop in temps. Why didn't they do it like this from the factory? Who knows?!

Solved major issues!!!!
After a new trans and new trans cooler, replacing the factory piece with this was the best thing I have done. Trans fluid temps are now down 80-100 degrees from where they where with the faulty factory piece.

Thank you for the review. Simple fix for a really bad factory design.

Great Product
Product was great, my transmission temp dropped from 167 F to 147 F and no longer gets hotter while sitting in traffic. Installation took 30 min with clean up and would recommend.

Thank you for the review. Agreed, the thermal bypass valve was a terrible idea on the part of Ram, fortunately, this is an easy fix to keep temps down.

Early, but working as described
Had this installed during my second transmission rebuild. So far tranny temps 40 to 50 degrees lower than engine oil temp. Time will tell if it helps prevent another rebuild.

Great product
Arrived quickly and awesome quality. Easy install, no special tools needed but I dont have factory exhaust so that could play a toll. Definitely brought exhaust temps down.

Do you have a install video on this product? I just ordered one for my 2017 HD2500 Ram 6.7L CTD.?

We do not have any install videos. But it is a very simple install and looks like it will only go on one way. DppSands

Will this fit the 66rfe transmission as well??

If they use the same valve I don't see why not. That has only been confirmed on the 68rfe and Aisin 6.7 Cummins trucks, DppSands.

Will this work on a 65rfe ram 1500, I fell that it should 65rfe 66rfe and the 68rfe all use the same system. Thanks Marco?

This product will only work on 68RFE and Aisin AS69RC transmissions. DppSands

Will this product fit a 2010 Cummins with the 68rfe?

No, this is designed for the 2013+ trucks.

I have a 2013 Cummins with the 68rfe would this thermal bypass valve delete be a good idea to add if my truck is fully deleted and has hpp 5 stage efi and rev max trans tuning or would trans tuning alone be enough, I dont want to go overkill, also would the valve body plate be a good idea as well if I have trans tuning I see there's alot of pressure modules an things like that to benefit the trans just want to know what's best considering I already am deleted and tuned and also have trans tuning thanks.?

Yes that bypass valve delete is a great idea, excellent upgrade for longevity of the transmission. I would definitely look at a gasket and plate kit also. When we up the line pressure on the 68's it can cause some internal cross leakage. That would cut that leakage down to almost nothing. And prevent the clutches from dragging. Thank you! DppSands
