00:00If you're rebuilding a transmission in your garage, you already know the solenoid and
00:04controller are where the real money goes. So I went through the listings and pulled
00:085 transmission solenoid controllers that DIYers keep buying again and again.
00:13First up, the 4E kit for the Subaru 2.5L Forester and Impreza, $49.81, and nearly
00:205,000 people have bought it with a perfect 5-star rating. What I like here is that it's a
00:25full kit,
00:26so you're not hunting down each solenoid and each part number one at a time.
00:30For a Subaru rebuild, that's the one I'd start with.
00:33Next is the 45RFE, 545RFE, 68RFE control solenoid for Jeep, Dodge and Chrysler,
00:40and it's the cheapest on the list at $27.16. Over 4,700 sold, 5 stars.
00:48It's an original refurbishment unit that covers three different transmissions,
00:52so if you work on more than one Mopar truck, you keep one of these on the shelf.
00:56Third, the Volvo OE2232-7063 solenoid for heavy-duty trucks, 24V, $67.85.
01:06This is a shut-off valve repair part that matches the OE number exactly, which matters a lot on a
01:1124V commercial gearbox. 4,000 sold, 5 stars and honestly, for an OE match heavy-duty part,
01:18that price is hard to argue with. Then the Mercedes 722.8 valve body for the A&B class CVT,
01:25$109.40 with a 4.6 rating. The big advantage is that the control unit, the TCU, comes with the
01:33valve body already assembled. So you're not trying to mate new solenoids to an old control unit,
01:39you swap the whole thing and go. Last one, the RE505A control unit and valve body for Nissan and
01:45Infiniti EX35, FX35, G35, all of those. It's the priciest at $179.03, but it also has the best
01:55rating at 4.8. Same story as the Mercedes, it's a complete assembly, so you install it as one unit
02:02instead of rebuilding piece by piece. Links for all five are in the description below,
02:07so check the fitment for your exact gearbox before you order.
02:11If this helped, drop a like and subscribe, I keep digging through these parts so you don't have to.
