In this video series, I rebuild a 42RH/A500 transmission. This is my first time rebuilding this transmission and I am bringing you guys a long for the ride!
Just bolted pan on tonight. Spent many hours playing and pausing your videos in the garage. My first home rebuild. Cost of shop rebuild was more than truck is worth. Good time to learn. Thanks again for the videos even 7 years later. FYI they make a small shaft with a detent on one end to hold ball in for rooster comb. Local transmission tech gave me one to use.
Wow! Great video series. I just watched the entire thing in one shot. Have to rebuild a 4l30e soon and your video inspired me to tackle this job. Never rebuilt a transmission, but I'll give it a go now!
+Darth Eyeball Thanks for watching the series! Good luck on your rebuild. As long as you have the rebuild manual and are meticulous, you should be okay!
+MattsMotorz I got a copy of the gm 4l30e manual at the ready. I am just hoping I can match your skills! Also subbed as well. Best transmission rebuild video hands down!
Hello teacher, a friendly greeting, your videos and tutorials are very instructive. I congratulate you. I wanted to consult you. I have a 2000 4.0 Cherokee with the A500 42RH transmission and I need to repair it. Please do you have the complete Repair Kits model I need for this transmission. Thanks greetings
Your video helped to get me comfortable to do my 42rh. You didn't cover rechecking the endplay though. The manual is not clear on wether the OD is installed for it. I assume it as because it is checked befot teardown with it on
Great video series, I redid my 42RH from watching your series of videos. You missed showing us literally only 2, unimportant, steps. Good job. Do you have a patreon orsomething? I wouldn't mind throwing you some bucks for the vids.
My 42re starts in second gear. You can put it down into low but it’s like first and second want to bind together. I don’t have overdrive hooked up right now but when you are driving and it shift from second to third it doesnt want to shift back down until you give it a lot of gas when it is stopped. Any input would be a great help.
Hi. How long did it take to completely rebuild this gearbox? I have to fix mine, guys did fit it wrong way on and damaged torque converter and pump.. The car was started and oil pump was full with metallic dust, so I reckon valve body is full and holes for oil to go from the pump trough the main body as well... Now I have to get valve body, oil pump and torque converter... Or even whole gearbox, don't know yet...
If it was me, I would do a complete tear down and clean every single component. But that may not be necessary depending on how much metal dust there was.
Hey Matt. I just finished the rebuild on my 42RH and I have one problem. The shift lever will not move. I have a feeling that the parking pawl rod is jammed. Can you give me any advice? Thanks.
@@leahyz yes I did. However, the rebuild didn’t work out as I didn’t have the proper tools for it. The rebuild wound up messing up just like the transmission did before I rebuilt it.
Matt: I watched all of your 42RH videos, which I think are the only ones showing a rebuild on that tranny. Thanks for your efforts, but I have some constructive criticisms -- hope you take them as positive, not negative. I cringed when I saw you rolling valves on a lint-y blue paper towel because I kept thinking of fuzzy bits getting on them and affecting their travel in the bores. I really cringed when I saw you driving bushings with a block of wood and then having to scrape the edges from the damage you caused. And I didn't see you test the bushings by putting in the corresponding shaft and then smacking the assembly as necessary to shape them, etc. I rebuilt my 4L60E and paid a local shop to remove the old and install new bushings -- much better route. I made spring press tools from oak and all-thread, and they worked great. Didn't figure I could do an adequate job without a proper set of bushing drivers -- couldn't justify their cost for one build, though. You have a lathe -- why not make your own bushing drivers when needed? At about the 21 minute mark, the manual valve was not moving when you moved the shift arm . . . is that right? If so I hope you spotted the problem before reinstalling the tranny in the vehicle. I've watched a ton of Hiram Gutierrez's videos -- HIGHLY RECOMMEND THEM!. The man is a tranny genius and a wealth of information, tips, tricks and insights. HG's vids have very good info on the use of assembly lube (he uses the green stuff to stick bearings, blue for lip seals), use of a lip seal tool (I made and used my own tool from a .010 feeler gauge and a small dowel, then bought the Snap-On tool, which obviously was an improvement -- both work better than trying to wriggle the lip seal into the bore by rotation, etc.), and a bunch of other things. I hope you had a successful build on your first 42RH -- I've worked on only a few Chevy/Pontiac AT's, so am most definitely not an expert. I'll probably watch your 4L60E vids to see how you did it, and some others to see what else you've done. Keep posting vids because everyone can learn from each other, and folks can share their experiences with you. Good luck on all your projects.
+John San Fellipo Thanks for the comments. Yes you are right, I really should have turned my own bushing drivers on the lathe. I really don't know why I didn't. I think it was probably because I didn't have and brass stock wide enough for most of the bushings and didn't want to pay to get some (so being cheap haha). I will say though that I have used wood to pound bushings many times and it has always turned out okay. I clean each and every part very thoroughly before re-assembly. It looked "hack-ish" as hell, but it has worked well for me. As for the valves on the blue towels. I really haven't had any issue with them either. They really do not release any lint or fuzzies at all. Especially when they are soaked in transmission fluid. But yes technically I should use labeled lint free cloth. Actually the proper way to do it is to have an entirely separate area designated just for re-assembly that it kept clean at all times. But this I cannot do. Yes I did fix the manual valve not moving. I should really put an annotation up there. Thanks for that. Lol the 4L60E videos are going to have more driving bushings in with wood so I hope you're mentally prepared for that.
+MattsMotorz Matt: Thanks for the response and for understanding where I'm coming from. I'll brace myself when I watch your 4L60E vids. Glad you caught the manual valve problem before you buttoned her up. How did the tranny perform? I put all my parts on clean paper -- the kids had a big roll for drawing, so plenty big enough and no fuzzy stuff. If I knew how to do machine work and had the tools, I'd probably look at making bushing drivers from mild steel bar stock -- would be cheaper than brass. Good luck.
Hey paper is a good idea! I can't believe I didn't think of it! The tranny runs great. My landlord (this is his truck) used it to plow the shop out a couple times this winter. It isn't his main vehicle so it doesn't get used too much except to haul some stuff here and there. It's a little funny because the truck is a piece of junk (and I mean piece of JUNK, runs great though) and it has this nice shiny rebuilt tranny in it. Haha. Yeah mild steel would definitely be cheaper, hell come to think of it, I had some aluminum in stock, I could have made it from that. I really think I was just being lazy and didn't want to turn a bunch of drivers if I am really honest with myself. I have gotten a lot of crap from people about the bushings, so next tranny rebuild I am doing it right to save myself from that lol.
