You say "the Sonnex spring is 126 thousands and nearly twice as big"...the
original spring is 63 thousands...63 times 2 is that is twice as
thick....not nearly...just saying...

Great video loving all the information, you guy's are awesome! Can you give

shift into third gear. I wanted to flush it out, any other suggestions that
might be helpful, I'm all ears..... Thanks Johnny

hey how can I get in touch. with you guys

I own a 1999 Dodge Ram 1500 that was not up-shifting properly. We did some
internet troubleshooting before taking anything apart to try to narrow down
possible corrective actions. We though we had a problem with the governor
pressure solenoid which seems to be a common problem. Luckily I ordered
this Master Kit because when I tore into my transmission I found the
Accumulator Spring broken. With the help of Cascade's video's I was able to
install the complete kit in my home garage in a couple of hours. The
quality of the products, fast shipping and very competitive pricing make
Cascade an easy decision.

I put one of these master solenoid kits in my '93 ZJ earlier this fall. The
kit is absolutely great, and Cascade has put good videos on youtube for
install. I really appreciated the 3-4 accumulator spring being heavy duty
as I found my OEM spring had shattered in multiple pieces. Some parts are
hard to reach, but my son and I were able to install all the parts in this
kit without pulling the valve body out. Thanks Cascade..

Author Roccar Morphs ( ago)
you say this upgrade the 3 to a 4 pin sensor. what
modifications are required to the harness to make this upgrade?

Author Jason Lewers ( ago)
Is that a Input Sensor ? I cant find the dang thing I have some whack
diagram that says the input sensor is where the neutral saftey sensor ?
It must be inside this is gonna kill me! I have took that 42RE pan off
like ten times To have rebuilt then fixed leaky pan bolts one agonizing
bolt at a time too see if fixed due too bugetarian regiments. I had a
master rebuild kit installed which is pretty much clutch bands O rings
springs etc Installed Feels Tight and Stiff! Now So where Im at I need
this kit and ....My problem is that It stalls but when I give gas does not
die kinda sputters then goes ok then shifts to second then down shifts
seemingly slippy without losing speed then after that shifts fine solidly
through too 3rd and other gears and does not really slip most the time I
mean some times it feels perfect Lets see how long it takes me too figure

@TCF2148 the harness can be swaped/replaced leaving the valve body in the
truck ; simply drop the 3-4 accumulator housing down to access the
connector - i welcome further questions if you email me directly from our

Author TCF2148 ( ago)
@TCF2148 Those are actually the solenoids in the upper left corner of the
frame as I thought. I'm pretty sure this does cover all the parts I'll
need, and it probably will be very easy. Next question: Since the 3,4
accumulator piston cushions the engagement of those gears, does the new
spring make it noticeably more harsh? (I should know this already)

Author TCF2148 ( ago)
@CascadeTransParts I was watching one of your other videos when you did an
RE master solenoid kit. You removed the valve body to replace the OD and
lock up solenoids. You mentioned not being able to get to the connector for
them without the valve body coming down. I must've mistaken the transducer
for the solenoids. Not surprising since this is my first automatic repair.
Well, the book says OD solenoid harrness, so I'll do a bit more research
before I start chucking parts.

Author CascadeTransParts ( ago)
@TCF2148 Hello , the kit can be installed without removing the valve body
which saves about 30 minutes ; simply drop the 3-4 accumulator housing to
access the connector , and replace - we are working on a supplemental video
to show more information

Author TCF2148 ( ago)
That's a decent kit. I've heard others praise the B&W solenoid on YouTube
as well. My shift problem I'm having with my "01 Ram 47RE is that it shifts
through 3rd in about a second under all speed and throttle conditions. The
shop manual for the truck says it's a short in the OD harness and since the
valve body has to come out for that, I'm just going to give it a full kit
and hopefully avoid opening it up again any time soon. I'll still install a
drain plug anyway, though.
