Bear with me a moment, if you will. And I need to stress this right now - the A604 likes cleanliness as much as a hospital surgeon does. Likewise, if you find one open, also replace the pack or you'll again get limp mode. If the set speed is exceeded by more than 4 mph 6. Couldn't be the speed sensors, I had just cleaned them of their debris.
This prevented random fill volume variation from causing poor shifts when the transaxle was new. The transmission only had clutches for gear changes, with no bands. This kit contains everything normally needed in a do-it yourself overhaul of the automatic transmission. Be the first to review this product! Each kit is a comprehensive reconditioning package featuring the best Sonnax products developed to help rebuilders restore and enhance transmission performance. The main filter could be clogged yet again, for all I know, even though I've only put 18,000 kilometers on this car since I bought it. It's just a bit slow on the very first 1-2, but there's no major hesitation all the way to the post office like there used to be. What else could it be? If that happens, the metal bars below them - the ones the coils magnetize to activate the blue arrowed valves - will move out of place and aggravate you when you try to get them to go back where they belong.
The transmissions do not have a valve body, technically, since the solenoids control the flow of transmission fluid directly. Normally, those sit all the way down in those holes on their beveled heads. Torque the mounting bolts down to 105 inch pounds, double checking the torque on all three before you reinstall the input speed sensor and reconnect the pack. Now that everything's been taken apart and thoroughly cleaned, it's time to start using the new parts. Then, take your new valve springs and set them inside the holes. Since I was rebuilding one from a 1992 Imperial, I bought the one above. They should go right down and nest inside the little brass pieces of the valves.
. Reasoning that all the car needed was fresh transmission fluid, I took a chance on the car and bought it. Also included is a calculation for fluid and air temperatures at start-up. And so, I did another fluid and filter change once spring came calling again, opting for just a pan drop rather than a full flush. No more machine guns under my hood. Clean, clean, clean around this area.
Ambient temperature, which significantly affects cooling, is measured or calculated. Until my 2001 Caravan, every one needed a rebuild at around 100,000. It was something I just hadn't considered as part of the problem. See those oblong holes in the bottom of the pack? It is the sheer length of these bolts that require you to remove the input speed sensor - they are very long indeed, and that middle one won't come out or go back in if the speed sensor is still there blocking it. I knew that they could be cleaned, but reasoned that new screens were probably an even better idea. The symptoms appear: hard shifts, slipping The drive home through the mountains revealed issues. I repeated this process several times, wiping things off with shop towels as I went.
An extreme close-up of a valve assembly. In doing so we have come up with several upgrades to revolutionize the way this transmission works. In the top half of the picture are the resistors and contacts where the coils connect. I didn't get that far into it. As used in the 2007-10 Chrysler Sebring, where they were paired with the 2.
No slip; it was fine. I inspected the shellac that was exposed to see how it held up, and it was fine. The high-quality Sonnax parts in each Sure Cure kit repair worn areas and protect the transmission against future damage. The filters and gaskets interchange. With the new fluid in, the transmission shift quality was vastly improved, but not all the way better. These problems are often the cause of switch codes and continuous limp-in complaints.
I want to keep this A604 on the road as long as possible before I have to talk to one. Most of the others had metallic debris collected near the tips. Here's a close-up of the input speed sensor, freshly cleaned. To eliminate bad seals, I added Lucas transmission fix, which has been known to help A604's with bad seals. Over time, this sound became so common that it was at one point abnormal not to hear it.
A point of interest - the cover on the solenoid pack stated that taking the thing apart would alter the calibration of the unit. Me, I used Brakleen on the case followed by several sprays from the hose. Pry the old ones out, push the new ones in, set the brass pieces back in the middle. The transaxle has a molded shifter with a top-mounted push button to operate the shift gate; roller detents correspond to transaxle lever detents. Here, I've removed the rubber seal. Why am I waxing nostalgic about the annoying buzzing sounds the older A604 solenoid packs make? How do you rate this product? Here, I've moved my radiator overflow tank and cruise control servo out of the way for better access. When the fluid was cold, the transmission would ever so slightly hesitate on its first few 1-2 and 2-1 shifts of the day.
Customer satisfaction is our top priority. By the time 1996 came around, you had to hold an ear right up next to the transmission to hear it. Clearly, my initial flush didn't get all the debris circulating through the transmission. Clean the hoses, the wires, the mounting brackets, and anything else immediately above the pack to make sure nothing goes awry when the pack comes off. The transmission used to bump shift when braking to a stop downhill at very low speeds. This stuff is extremely sticky, but it won't get all over the place when you apply it. The car shifted pretty well, but would slam in and out of overdrive in the mountains when transitioning between downhill and uphill climbs.
