42RLE Banner Rebuild Kit 2006, new and ready to install. Fits the 42RLE. Ships fast from the USA.
A 2006-or-later 42RLE that clunks on a 4-3 coast-down, takes a second or two to grab Reverse, or shudders and sets P0740 on the highway is usually wearing out in two places at once: the clutch packs and the valve body. This kit is put together for exactly that job. The box holds a complete overhaul gasket and seal kit, a set of high energy friction clutches, three molded pistons, a new filter and a TransGo SHIFT KIT valve body repair kit. It is meant for rear-wheel-drive 42RLE units in Jeep models, the Dodge Dakota and the other trucks that used this four-speed from 2006 on.
The 42RLE is the rear-drive member of Chrysler's Ultradrive family. Like the 41TE it has no bands; underdrive, overdrive and reverse clutches drive the gearset and the 2-4 and low/reverse clutches hold it. The controller learns how much oil each clutch needs to apply and times shifts around those learned volumes, so worn frictions or a leaking piston seal show up as flares, slow engagements and eventually a default to second gear. The frictions and seals in this kit restore the clutches themselves. The molded pistons replace apply pistons whose rubber lips have hardened with heat. The TransGo kit targets the valve body side: TransGo states its 42RLE-VLP kit uses drop-in pressure regulator and TCC regulator valves with longer lands that ride on unworn bore surfaces, a tuff seal and expander for the underdrive inner piston seal, and a no-shrink gasket for the low/reverse piston housing.
Scan for codes and read the clutch volume index values first. High numbers on one clutch point to wear or a leak in that circuit; a high low/reverse value together with a slow Reverse fits the piston retainer gasket leak that Transmission Digest describes on this family. A unit that slips mainly under throttle may have a pressure regulator problem rather than burnt clutches, which our guide to Ultradrive slipping under load explains. Electrical codes with clean fluid lead back to the solenoid pack instead; the 41TE and 42RLE problems guide covers how to separate the two.
The kit is listed for 2006-and-later 42RLE transmissions. The important variation in that range is variable line pressure. Sonnax notes that the Ultradrive family gained electronic line pressure control starting in 2007, identified by an extra connector on the case next to the range sensor connector, while TransGo lists its 42RLE-VLP shift kit for 2006-17 VLP units and says units without the line pressure solenoid and sensor need its SK 604 kit instead. Check your case for that extra connector and compare it to the TransGo part number on the box before you start. Earlier 2003-2005 units are better served by the 2003 42RLE banner kit. Send your year and VIN with the order if you want fitment checked, and see the 41TE and 42RLE collection for the rest of the unit.
Follow TransGo's instructions for the valve body work and install the new pressure regulator and TCC regulator valves before the unit goes back together. Soak the frictions in ATF+4, fit the molded pistons with clean fluid on the lips, and set every clutch pack clearance to spec. Inspect the planetary carriers for blued or loose pinions while the unit is apart and replace them with the 42RLE planetary if needed. If the valve body bores are too far gone for a drop-in kit, the 2006 42RLE valve body is the alternative. Fill with ATF+4 only and check the level hot. TransGo's tech note says to reset the line pressure counter, clear codes and run a Quick Learn before the road test on VLP units, and that VLP 42RLEs built before April 28, 2008 should have the latest PCM software.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
An overhaul gasket and seal kit, high energy friction clutches, three molded pistons, a filter and a TransGo SHIFT KIT valve body repair kit.
It is listed for 2006 and later units. For an earlier 42RLE use the 2003 banner kit, or send your VIN and we will check which kit matches.
Look for a second electrical connector on the case beside the range sensor connector. That connector feeds the line pressure sensor and solenoid. TransGo makes a different shift kit for units without it, so match the kit to your case.
TransGo ties that clunk to a failing underdrive clutch inner piston seal, and its kit includes a replacement seal and expander for it. Worn clutches and valve body bores can add to the complaint, which is why the kit covers both.
ATF+4 only, with the level set at operating temperature. On VLP units reset the line pressure counter, clear codes and run the Quick Learn with a scan tool before driving.
