41TE Shift Kit 1988, new and ready to install. Fits the 41TE. Ships fast from the USA.
Owners of Dodge Caravan, Grand Caravan, Plymouth Voyager and Chrysler Town and Country minivans, plus Stratus, Sebring and other front-drive cars with the four-speed A604/41TE, tend to search for the same complaints: a pause before it grabs Drive or Reverse, a bump as the van coasts to a stop, or a trip into limp mode on a hot day. This is the TransGo SK 604 SHIFT KIT (the 604/42LE kit), new, for the early and middle years of the 604 family without variable line pressure. It ships from the USA.
The A604 was Chrysler's first fully adaptive electronic transaxle. It shifts by handing torque from one clutch to the next, and the controller adjusts those handoffs based on how much oil each clutch takes to apply. That makes it sensitive to small leaks. TransGo says they burned up a test van many times over 60,000 miles before concluding the design had no single big flaw, just about ten small things that need attention. This kit covers the hydraulic ones. A non-shrinking low/reverse piston housing gasket replaces the factory gasket that shrinks and leaks. A self-expanding underdrive piston seal with an expander wire stops the leak behind the 4-3 coast clunk. New high-temperature seals and expanders reseal aluminum accumulator pistons, and spacers in the accumulator springs let the releasing clutch exhaust sooner for shorter shifts.
One piece matters most on the oldest units: the kit includes a new pressure regulator spring that brings 1989 to 1991 valve bodies up to the revised pressure specification Chrysler used from 1992 to 2006.
Codes P0841, P0871, P0988, P1775 and P1776 on a high-mileage unit usually point to a worn solenoid switch valve bore, which this kit does not repair. Electrical faults in the solenoid pack, wiring or range sensor are also common on the 41TE and should be checked first.
Scan for codes and read the CVIs. On this transmission a high CVI for one clutch means that clutch is worn or leaking, and the pattern tells you where to look. If the CVIs are in range and the complaint is a delayed engagement or coast clunk, the gasket and seal fixes in this kit are the likely cure. If they are high, plan a rebuild and install the kit during it. Our 41TE / A604 limp mode and CVI guide covers the code and CVI checks, and the 41TE slipping under load guide walks through low line pressure and underdrive circuit leaks.
TransGo lists SK 604 for the 604 (41TE), 606 (42LE) and 42RLE without a variable line pressure solenoid and sensor, 1989 through 2006 on the front-drive units. The 1988 in this listing marks the beginning of the A604 family; TransGo's published fitment starts at 1989. Later 41TE units with a pressure control solenoid need the TransGo SK 42RLE-VLP kit, which TransGo lists for VLP 604 models as well. The valve body tells you which you have, and so does your VIN; send us the year and VIN if you want us to check. Every part we stock for this family is on our 41TE and 42RLE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A 1998 41TE is a non-VLP unit, which is what TransGo lists SK 604 for. Send us the year and VIN if you want us to double check before you order.
It marks the start of the A604 family. TransGo's published fitment for SK 604 is 1989 and newer 604/41TE and 606/42LE without variable line pressure, up through 2006.
Yes. The kit includes a pressure regulator spring that updates 1989 to 1991 valve bodies to the revised pressure specification used from 1992 to 2006.
Only if the cause is hydraulic leakage this kit seals, such as the low/reverse housing gasket, underdrive seal or accumulators. Limp mode from solenoid pack, wiring, sensor or switch valve bore faults needs those parts repaired.
ATF+4. Then clear codes and run the quick learn with a scan tool before the road test.
