> [@davesmopar](#): > > Chunks of metal are never a good thing… lol Indeed. I was thinking maybe some grain sized things aren’t so bad, except that those should end up on the magnet. But the one the size of half a pinky nail? That’s bad. If you really want to keep this on the road (improbable with its age and mileage) then you’re looking at a rebuilt tranny. Other than that, you can try to limp it along with mechanic in a bottle. But don’t expect any miracles. Note that the “mechanics in a bottle” stuff are not all the same kind of thing. Something like Seafoam “transtune” is basically a cleaner and thins out the fluid. Something like Lucas does the opposite. It’s thick and sticky. Which you try is basically a crap shoot without a real diagnosis. E.g. sticky TCC solenoid messing up line pressures? You want Seafoam. E.g. worn clutches, you want Lucas. Both are band-aids on amputations, if they do anything at all. ---

I could take pictures but can’t put pics on here. I would go with a used tranny if I can find one. ---

It’s a 4T65E tranny. 05 park non supercharge only works. Not any other year make or model. Did find a used one if needed 100 miles away. 94,000 miles $400 w exchange. ---

Other cars have the 4t65e and the rebuilt kit is the same for many others but supposedly 2005 was designed differently in some way than all others. How hard is it to rebuild these on your own? I have a buddy who could probably help me do it. Kits only 100. Is that everything needed in this kit? eBay part 296431813556 if link doesn’t work. > **[4T65E Transmission Rebuild Kit Fit for 2003 Up Exedy Clutches fits GM | eBay](https://www.ebay.com/itm/296431813556?_skw=296431813556&itmmeta=01JBYJ03H366TZPYGBKS3MW3AN&hash=item4504b683b4:g:u0wAAOSwz09mQxwV&itmprp=enc%3AAQAJAAABEHoV3kP08IDx%2BKZ9MfhVJKlXIwCU5vDzEnqKtJ%2FF8TH4--aBX4HP0FFDexHzpEX%2FT5Gl--kOjc0mSseFtK5O4Q0hNQzsbAG0ZhCsdWYzUi9fJSNNkfUP8G%2BggcdwIqTOCj4xDuUFojwXQCjOGWRwsPnt1H%2Fa1Q95zVh67f9zfjOHMUnTT7CndBgMMaRn%2B%2BRYgeQyfEG1wN%2FN7qxF4KSWsAV%2FxryJMQ9p3Fo1jCloVPWE2NIy%2BAvKawDiz8o4hznvQPlSLlL7U%2BLJFzoZs6uSvKm7PwbWaaTg32pucofJE8%2Fn6MUrGLYXXjIS89E%2B82iNYHxxDxSou8WcbyhPVyqLBQKNIP3uldANNN%2BkRxg9REaQ%7Ctkp%3ABFBMyriA0t9k)** > > 4T65E T84002GX Transmission Gasket Seal Rebuild Kit for Century Regal Impala. 4T65E Transmission Gasket and Seal Rebuild Kit 1997 Up fits Impala Malibu Azek.

I would think a rebuild kit is for normally worn parts, not mechanically-failed parts like yours. I’d think you need a rebuilt transmission, not rebuilding your transmission. ---

I would spend 400 for a used one with under 100,000 b4 spending a few grand. Does anyone know what those pieces can be? ---

The pictures are a bit blurry, hard to see, but it looks like a thrust washer(s) or bushings, not good IF it is… But with ANY automatic transmission, it has to be torn down to know what all it will need when a hard part fails… Here is a picture of the internals of your transmission… you will need $$$ in specialty tools that auto parts stores do not carry… Most mechanics can not rebuild a transmission, even harder for a DIYer… But if you are feeling froggy, jump… lol And the fun part is, you can cut/tear a lip seal or install1 of many parts wrong and you wont know until the test drive… ![Screenshot 2024-11-05 125003](https://global.discourse-cdn.com/cartalk/original/3X/a/3/a30443ff9172889f9741489a3fcca8498830cddc.jpeg) Your kit at a minimum is missing all the clutch Fabrics and Steels, thrust washers, bands, bushings, clad seals, sprag kits etc etc etc, should be around $500 for the most complete kit plus any number of hard parts, your kit doesn’t even have the filter or side cover gasket… You will also need a new/reman torque converter… You could easily have $700 to a $1000 in parts not counting special tools… The last 4 speed auto I built, it was cheaper to buy a $300 rebuildable core and use the best of the 2 transmissions plus the rebuild kit and torque converter… Your kit is basically a very basic reseal kit, it has zero wear items other than basic seals it is not what you need… ---

If you look through @davesmopar whole post…there’s pretty much no way you’ll come out ahead trying a DIY rebuild. It will be a lot of time, money, and aggravation. You’re odds of success are minuscule. And even if you did miraculously pull it out, in the end it would have been both easier and CHEAPER to just get a used one - with all of the “crap-shoot” that comes with that. I had a 4T65E in an Olds minivan (don’t let the outside fool you - same basic drivetrain that you have). And as I think I mentioned above, when mine had TCC lockup and hard shifting issues - even without any metal in the pan to speak of - my local transmission guy told me he’d given up and just orders remans with a warranty on them. So not only do most mechanics not rebuild trannys (as Dave said), this was a transmission specialist who wouldn’t rebuild 4T65E’s ---

If needed I will get the used tranny and hope for the best. If it’s gone 230,000 miles can’t be the worst tranny in the world. ---

I seem to recall a few days ago you said you never bothered to service the transmission fluid and filter before this current situation . . . ? If I’m wrong, please accept my apology ---
**Author:** ![cigroller](https://avatars.discourse-cdn.com/v4/letter/c/c68b51/32.png) [@cigroller](https://community.cartalk.com/u/cigroller)\ **Post date:** [November 6, 2024, 3:18am UTC](https://community.cartalk.com/t/transmission-shifts-hard-jerks/197790/56 "2024-11-06T03:18:21Z")
If you go the used route, drive it a couple hundred miles and do a pan a filter service. Then drive it like another 500-1000 miles and do that again. Who knows how long its been sitting, how old the fluid is, or whether or not it was ever serviced before. Also look around the web for solutions for recurring P1811 hard shifting issues on the 4T65E that involves new accumulator springs out of a TransGo shift kit that are easily installed with a pan drop. (This is only part of the kit). With the metal chunks you found, you’re past that with your present tranny. But if you get a used one, and drop the pan, then throwing in those new springs whle you’re in there is is a good idea. The link I used to send people is dead…but its out there. ---
