You don't have to drill out and damage a stubborn aluminum accumulator cover- the hole in the end is a common pilot size for pipe thread. Tap it with a pipe tap and use a slide hammer to remove the cover intact. Never came across one that wouldn't come out. I was able to clean up and re-use every one (fresh O-rings please)
Do you know of any performance upgrades for this transmission? These units are right at their normal limits in the heavier Isuzu vehicles and when you start pulling trailers or doing any sort of serious off-road driving, they tend to die at accelerated rates, usually losing gears. They do come with factory trans coolers. Later Rodeos/Axioms and the Vehicross came with the better Aisin 30-40LE but lots of Rodeos/Amigos and Troopers out there are running around with the light duty GM unit.
Gary, with your videos, I have partially disassembled a used 4L30e and put it in to replace a shot transmission in a 2000 Passport. Thank you! It runs great, but it leaks and at certain times will spray fluid on the driveshaft (front) and passenger underside of vehicle. I believe it is the accumulator piston cover leaking badly. It is the bonded rubber style and I am ordering a replacement. Questions: 1. Can I temporarily seal it with something so it will be driveable until it arrives? 2. Do I need to remove the piston and change the o-ring on that also? 3. I think it has lost about a quart or so. No trans lights and the fluid looks good. In your opinion, is the transmission damaged from the fluid loss? It still runs good with filled fluid. 4. Is it unusual to get spray from this leaking cover? Sorry for the long message!
I would say no, no temporary seal that i know of. If the o-ring is good, you can leave it, be careful when putting the piston back in, there is no chamfer. if it runs ok, you should be fine, just keep it full. i have never seen spray(check cooler lines if one is near ) just constant drip
Gary I have a BMW 535d auto .driving along the engine rpm jumps up and down by around 500 rpm and it sounds as if it's changing gear .The problem seems to be worse when cold .It also does it in over,run but not as severely .Any help or info would be appreciated thanks Damian.."..
Gary Ferraro there were 2 engine related codes ...glow plugs and back pressure sensor nothing gearbox related.The car is 06 is there any way of a gearbox re-set. there is just over 100.000 miles on it. Do you know of any type of engine fault that could cause a fault like this
Gary I have watched your videos on the 4L30e I am currently in need of some tips on installing the center support for a 2000 Elantra A4Bf2 There are no manuals to find how and which direction the bell spring goes behind the Center support Concave up twoward pump or concave faing the rear of the unit Any help is appreciated Pete auto teacher western High school NC
I've got a 4l30e in a 2000 passport. Interesting question. I can put the rear wheels up on jack stands and crank it up and it will drive and shift through all the gears perfectly. But when it's sitting on the ground I only have first and reverse and they are strong. It's like it won't shift into second, put up in the air everything works fine. Could this be a slipping band or low hydraulic pressure? No check engine light. Fluid looks fine. Thanks for your input.
@@GaryFerraro yes I had put "a" shifter solenoid in it a few years ago and it didn't fix it. I had top the fluid off then but it wasn't running. Since then I pulled it out and started taking with it again and I topped the fluid off with it running.
@@GaryFerraro I'm not exactly sure what the low band does and it could be out of adjustment. I'm going to check that while I have the pan off currently. I have all 5 solenoids on order to replace.
@@GaryFerraro interesting, while 1st gear is strong then that's probably ok. Hhmmm.... I could have installed a faulty A solenoid before or maybe the epc is sticking closed decreasing pressure? I even tried driving it down an incline to see if the gravity rolling would allow it to shift to second and no such luck.could have made a difference if it was a pressure thing since it does great on stands.... in a few days I'll get the 5 solenoids in and low band checked then refilled and we'll see I guess. Could be the tcu/ecu. That's my next check once back together if it's still quirky. Speed sensor? I'm reaching. Abs code says rear speed sensor not working, does that play a part in the transmission or just the speed sensor on the transfer case?
Dear Gary, i have a question about zf 6hp19a transmission.... the problem is abnormal rpm cycling when transmission is cold... when it gets warm it gets better, transmission has a new valve body and bushings. Can be the torque converter cause of the problem?
I think that the engine is running right... there aren't any codes for it..... and sometimes it produces some strange noise in fifth gear, the e clutch drum is also checked and there aren't any cracks.
Hey mate I'm going to attempt a rebuild on this transmission to save some money, can you tell me who you recommend for parts/upgrades I should do while in the transmission
@@breezekin1996 Can you scan the car to see if any codes are present? I like TransTec kits, go with a Banner kit. Reuse the EPC Solenoid but change out the other 4, change the LOW band but watch the Ajustment, you need a tool to line up the pump but if you don't have could probably use converter. How much do they want to rebuild the trans?
friend I hope you can help me I have an automatic izuzu 1995 and it has time that broke the trasmicion. only enters first and second and when you want to enter third neutralize the change of fuel and filter and wanted to grab third but time remained the same only this time when I accelerate thoroughly on the highway jump from second to fourth I hope you can help me from Mexico
interesting - but i just make my own covers on a lathe and anodise them. they work just fine. I've run into a lot of these transmissions where the third clutch drum just blows the top off. but i have a fix for that too. can't understand why they just don't make things out of proper materials. cost i guess.
Gary good evening. Have a question regarding a 3l30, when hot it bangs into drive and reverse, but what's really got my attention is that it shifts from 2-3 really quick, from 1-2 shifts great at about 10-15 mph once it shifts to 2nd gear 3rd gear comes up real quick and engine sounds like it's bogging. I changed the modulator and I took the transfer out to check the governor valves, and they are free, but there was no gasket at the governor body, can a missing gasket on the governor body cause erratic shifts ? Or could I have a problem in the valve body, thanks in advance Gary. Oh and it's a 92_93 geo tracker 4x4
@@GaryFerraro in my workshop manual it depicts a image of a tool that helps push the rubber cover in to seat the snap ring,the special tool number is " J-38559-a" no google search came up with anything
@@WorkableWax Just looked in my tool catalog under 4L30E, saw nothing for that. I use STP oil treatment and a socket to push that down and install snap ring, not easy , sometimes i have to tap it lightly with a hammer
I cant express enough how informative your videos are! Thanks for putting in all your effort!!

with no load on the car it may shift on the lift, trans full of fluid?

Can these transmission last 300,000 miles with the proper fluid change and filter? In your opinion of course!
I have one of these with 215k miles on it.. Has the common 3rd gear issue but it still runs great even down highway speeds

No there aren't any codes present... valve body is new with new solenoids.

if the same happens when it is hot and cold.
@@octaviomartinez4556 sounds like that direct clutch is no good. That's the clutch in the small drum
