4L30E Disassembly 

Without this video I would’ve never known where the check balls were supposed to go, since they fell out when I removed the plate. Doing gods work! Thank you

This dude is a bad ass! Love how he knows all the parts positions 😮

I’m currently in the process of repairing my gfs rodeo transmission. It had been rebuild before but they missed the thrust washer that goes on the bearing between the second drum and the sun gear, so the bearing exploded and took the planetary gearset with it. Amazingly all the clutches and everything else is in mint shape. Your video is super helpful

hey tom this is Brian if you see this message I use to work with you at AAMCO in Everett wa. if you don't remember I was retiring out of the army and now I have my own build shop in mossyrock, wa. WE JUST STARTED SB AUTOMOTIVE AND THANKS FOR ALL YOUR GREAT KNOWLEDGE AND EXPERIENCE YOUR SHARING.

good catch on the backwards sun gear.. and without a Manuel....amazing..

Wow ...usted es todo un maestro ...gracias por hacer este video y compartir...

Só um dos angolanos que gosto tanto de assistir os seus trabalhos

Excelente video 🎉🎉🎉

Hello Tom, great video! I have an 00 Passport with this transmission that was sitting in a garage for years. It shifts perfectly up and down all the gears when it's cold, but as it warms up it will lose overdrive. It'll shift out of 3rd, but OD won't engage and it'll look like i flipped into neutral. This only happens after running long enough for the transmission to get warm. Any ideas on the fix?

Gracias muy bueno excelente

Muy buen video

Hello Tom, I love your videos! So I have this Isuzu Rodeo 4x4 with a 4L30E that only runs in 1st gear forward and reverse, but no 1-2 shift or any higher. At about 2500rpm the first gear just disengages and the engine runs away unloaded. I have replaced the 1-2 and 2-3 shift solenoids but still no improvement. The oil pan was reasonably clean and no major metal or friction material in it, and the Rodeo only has about 85K miles on the odometer. What could be the problem? Thanks!

I know this is old but I took my pan down and the filter. All the way to the main trans body. The check balls fell out. How can I have the one stay in while I have it all upside down?

Hi Tom, my 2000 rodeo has same transmission. My problem is my car could not go up, I can drive only flat land and also so slipper clutching even that surface. I guess my clutches burn out right and need to replace? Should I also change all the solenoid valves or just enough couches and o-rings ? Thanks in advance

TCT .... my 4l30e dosent engage 1 n 2 gear , i have to drive it in power mode "3rd gear" , intrenet says solenoid for 1st n 2nd gear or band adjustment needed , what do you recommend ..........TIA ....

Howdy, Tom-I am into a 4L30e out of an 02 Rodeo, fun little machine. I was having 2-3 flares and ended up putting the translab shift correction kit in it. Kinda fixed it; sometimes flared, sometimes not. Fast forward to yesterday and blew the OD accumulator cover out, had my own little Exxon Valdez in the middle of the street. Got it out and torn down and surprisingly most of the frictions look good with exception of a couple of 2/3 pack frictions and steels. The OD planet ring gear surface where the thrust washer looks terrible as well as the washer. What would smoke this thrust washer/ring gear surface (maybe incorrect end-play somewhere? Also, I cant seem to find the actual piston replacement for the OD accumulator, only the cover-is this by design? Would love if Sonnax had a pinless for this. Anyhow, its getting all new seals/steels/frictions/bushings/bearings/TC; anything to which I should pay special consideration during this? (I plan on putting the superior & Transgo kits in this as you have noted. Thank you!

if you had to make sure you did a good job on an unknown tranny history with a kit which one would you get and what other things might you get that the kit doesnt have? I am going to try to do this myself. Also are there tutorial vids on the 4l30? And are their connection kits for the different vuhicles these trannies come in? Thanks in advance

02 rodeo v6. I have a 3-4 flare. What's the typical cause of it. Just bought it used 119k on it. I'm going to replace fluid, filter and clean the solenoids.

Fantastic Video Tom. I need some advice with my 4L30E. It is throwing up "error 100 - Gear Monitoring" with thumps in the drivetrain when shifting. Can you give me any ideas on what the problem may be?. Thanks in advance.

So what happens when the pump washer breaks? I found mine in 4 pieces in the overdrive pan when I was replacing the solenoids.
