Leaky brakes, or bad axle seal?
Likely to be axle/wheel seal. Just a few months ago I had to do the rear axle seals in the middle of a 2000 mile roadtrip. TorqueKing.com has everything in one kit at a reasonable price.- 70UTE

66RFE TROUBLE
So the saga continues, 600 miles in on the rebuild and the overdrive clutch assembly failed, the clutch hub welded itself to the new sonnax bushings. Bearing material in the pan and filter. Ruined the new converter as well. After the rebuild I was having the same issue as I originally started...- 70UTE

66RFE TROUBLE
Update: rebuilt the transmission in the garage last week and installed over the weekend. Test drive today for about 20 miles after fluid fill and relearn. Used an OEM rebuild kit with the updated TSB provided by mopar in the kit. Sonnax valve body, sonnax bushing and Torrington bearings. Moses...- 70UTE

Can the 66rfe be rebuilt with a 68rfe rebuild kit?
https://youtu.be/GIEz_yWtQDk?si=3Rth-3KtBDrKpBl6 Watch that video and it will answer the questions you’re looking to get answers for. If you’re looking to DIY, it’s a pretty user friendly transmission to do at home given you have a few specialty tools. There are OEM kits that come with the TSB...- 70UTE

66RFE replacement expectation
Walking a similar path as the OP. I have a real problem with my 66rfe although it is drivable. Went to the local Ram service center and they quoted 9.5K for trans, cooler, shift cable and 10 to 12 month wait time not including R&R. I just ordered my rebuild kit, have the sonnax valve body and a...- 70UTE

66RFE TROUBLE
https://share.icloud.com/photos/01dIeFvQ-NLvtKsWQ2x9UmScQ I don’t know how well this is going to work but here is one example of the issue I’m dealing with. Only giving it part throttle, rpm loss but continue gaining speed.- 70UTE

66RFE TROUBLE
Dropped it off with the local Ram service center. Explained the entire dialog with them. They completed a relearn and “software update”. Completed a test drive and was able to repeat the rpm loss while accelerating and driving under load. Interesting that they could not find a single thing...- 70UTE

66RFE TROUBLE
Unfortunately I have to agree. I think it’s time to do it before it grenades and turns into hard parts replacement. Until I make a decision it’s back to the Tacoma for daily use.- 70UTE

66RFE TROUBLE
I tend to be on the proactive side of fluid changes. Oil is done at 4500 no questions. Trans is between 20 and 30K. Agreed that there are many differences between the two but I’m over particular about scheduled maintenance.- 70UTE

66RFE TROUBLE
No burnt fluid and the filters and pan magnet look good without much buildup. I grew up in a transmission shop, my old man built everything from powerglides to 68rfe and everything in between. I’m not big on modifying outside of OE unless it’s a true problem solver. I’ve monitored this thing as...- 70UTE

66RFE TROUBLE
I’ve gone through this thing as best I can without a complete tear down and rebuild. The truck is a 2013 5.7 66rfe 4x4. I have now 100K on the clock. When I bought the truck I didn’t notice it right away because I don’t hammer on the gas. What I have issues with now is lag/slipping during hard...- 70UTE

Anyone tried the ball joint delete option?
I have the American iron off-road delete. Haven’t had any trouble with them going on 10k miles. They’re expensive but so far so good. 2013 Gas 2500 if that helps.- 70UTE
