Product Description
Fix one of the most common failure points in your Dodge Ram transmission with the TRANSGO RFE-SV453-NT Solenoid Switch Valve Repair Kit. Designed specifically for Chrysler RFE transmissions, this upgraded .453” valve kit eliminates sticking valves, restores hydraulic integrity, and prevents costly transmission failures like limp mode and overdrive clutch damage. This kit includes a precision oversized hardened steel solenoid switch valve along with upgraded end plugs and spring to correct bore wear and restore proper transmission operation. The redesigned valve prevents sticking and helps eliminate trouble codes like P1775, P1776, P0841, P0846, P0871, P0876, and P0988. If your 68RFE or other RFE transmission is experiencing erratic shifting, no lock-up, or limp mode, this is one of the most cost-effective and proven fixes available.

FAQ
What does the solenoid switch valve do?
It controls fluid routing between the low/reverse clutch and torque converter clutch. When it sticks, it causes shifting issues and limp mode.
What symptoms indicate I need this kit?
Common signs include limp mode, delayed shifting, no lock-up, harsh shifts, or transmission codes like P1776.
Does this kit require transmission removal?
No. Installation can be done without removing the transmission, making it a quick and cost-effective repair.
Do I need special tools?
Yes. This is the “NT” version and requires the .453 reamer tool. If you don’t have it, choose the WT version.
Is this better than replacing the valve body?
In many cases, yes. This kit fixes the root cause (bore wear and sticking valve) at a fraction of the cost.
