8hp70 bypass stats

[Dan Topp]

Thanks to a tip from Wild one I bought the bypass and the trans temps are hard to believe but what’s harder is that I was so stupid to put 40 k on a new truck that is stupidly designed to cook the oil and itself.Did the 119” belt and brakes and rotors too.

This is why it finally had to be done. February in Texas.Still have to get a oil cooler then it might be safe.

Good on ya. This forum has been invaluable to making Ram trucks live. Jesse Caulk is one of the heroes here.

 

[EdGs]

I've seen Jesse's bypass on some of the YouTube Ram videos, "10 things to do to your Ram", etc.

His bypass is listed as beneficial.

They do not show a picture of it, though. They also show other engines and parts that are not Rams.

I didn’t include the getting hit in the eye when it finally decided to come out and the trans oil hair treatment,but only a few ounces of fluid is actually lost.

Improved Racing has some nice stuff if you're looking at adding a stand alone oil cooler Dan.
Their oil thermostats have one of the better reps in the industry

High-Flow Engine & Transmission Oil Cooler Thermostat

Thank you I am juggling the b&m with thermo controlled fan but I like the temps to get above 180 for engine oil so I will check them out.

They have these 2,that are probably close to what you want. If it was me,i'd go for the one that stablizes at about 205,that gives you a bit of leeway for towing or working the engine hard,it goes to full flow mode at 221.

FSM-205	205ºF (96ºC)	200ºF (93ºC)	221ºF (105ºC)	Engine Oil (Street & Strip)
FSM-215	215ºF (102ºC)	212ºF (100ºC)	233ºF (112ºC)	Engine Oil (Road Racing)

I think the 205 will be good on my other build too,nice cooler setup for vettes

I was bragging early about my caddy having low trans temps .Doing some light towing on a trip to Newport state park and half into the trip the trans is 185 hope it doesn’t get worse it only has 6900 miles on it and I wanted to wait till 10k to change the oil.

 

[EdGs]

I eliminated the coolant flow to the transmission heat exchanger on my '15 SLT. My trans takes a good bit to heat up.

After cruising a fair bit in the afternoon, I start seeing 180° trans temps. Sometimes it will only be 140° or less after my ~25 mile commute to work.

I do have one of Jesse's bypass kits and a PPE pan to install, but have not had time (or energy) lately. I also want to get some more juice so I can do a drain and fill before I swap the pan, but might just have to do it later.

Hey Wild One, I see you hooked up Dan Topp on the trans t-stat. I like his results. I do no towing but want the tranny to last. Currently runs 186 to just under 200F in stop and go traffic. I will be having a trans service in about 5K (have 49500 miles now). Do I buy this part strictly from a Jesse Caulks web site, summit etc...? I found the part at a site called Improved Racing for $199. Also what temperature rang t-stat am I looking for?

Do Jesse's bypass,it's all you really need to take alot of heat out of the fluid.

Just have good snap ring pliers and a replacement ready since the kit doesn’t provide a snap ring.

Did you re-use the old snap ring (if there is one, I'm not sure, never done this job)? Just asking because I have the kit sitting on my bench. Gonna order the PPE pan and fluid soon to do this job. Do I need to also buy a specific snap ring? Thanks..............

You should be able to reuse the existing snap ring, as per the installation directions.
You can download them from the distributor's site.






I finally took the plunge and ordered my kit.
