90 S10 BLAZER 4X4 LIFTED. They are a bit rare here, but do come up occasionally. Many of the older solenoid blocks were prone to copper windings burning out internally, as well as weather-proofing concerns. Points: 5794. 6 Signs of a Failing Torque Converter | Ralph's Transmission. manually downshifting from 3rd to 1st? I'll check the converter bolts just in case, but it still doesn't take away from the fact that it's not wanting to move in drive when cold until it warms up or I rev the engine, then after a mile or two of driving, it acts like nothings wrong with it. Remanufactured C6 Transmission Updates and Upgrades. Transmission must be removed and rebuilt, sooner rather than later.
Sounds like bad TC and agree that the fwd piston seals or seal rings might be dieing. That may be all you need to get fresh fluid running through the system again. Debris in the fluid/screen can cause issues.
Soft shifting, gradual performance degradation: Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Drove it for about a year doing that until I put a SBF c6 in it. I only hear the chattering sound when decelerating though. It is drivable until it breaks.
This helps the transmission identify when it's slipping more accurately. Remove transmission and rebuild, or refill pan and find the leak. I've done the filter, fluid, adjusted the intermediate band per the manual and even changed the modulator, and this condition still exists. Last edited by jimwrye; 11-14-2020 at 02:52 PM. Thought I was being to paranoid. There are at least 3 C6 tailshaft lenghts. Before the Late 4L60-E transmission, there was the Turbo 700R, which was introduced in 1982. Although you may have some of these symptoms / problems with your 4L60E Transmission, the repair solution may differ. Ford C6 transmission issue - doesn't want to drop into gear from park. When delayed engagement occurs, the transmission's clutches and bands do not operate instantly. The external solenoid VB's are supposed to be quicker, I think because they do not use the 2-3 shift valve to apply the hi-direct drum like the internal solenoid VB's do.
90 class), and at that time, SST was run on a 4/10s Pro Tree, ( it has been changed to a 5/10s Pro Tree for many years now), but on the 4/10s tree, the Art Carr brake simply did not release quick enough for the 4/10s tree, and even with the use of ridiculously short 22" tall front tires, and eliminating most of the front suspension travel, my lights were not good enough. I had a sticky convertor drain back valve years ago that caused this. Was it full enough of fluid?? How to rebuild c6 transmission. If the valve body gets refried to many times, it can be a problem, and on an old 70's transmission, it likely has been. However, this could result in severe damage as an increase in speed in your engine creates friction that may further damage clutches and bands. Or it could, you equoia wrote:Nooooooo! They are often reliable on day one, but quickly lose their ability to produce pressure quickly, predictably and effectively. Even if nothing "breaks", these transmissions are challenged to survive past 150, 000 miles before quickly degrading.
Twin Automotive & Transmission, Charlotte's Transmission Specialist, provides free transmission repair diagnostics (diagnostic is free with repair of the transmission). Ford had to totally redesign the valve body to allow for the usage of a 4th gear overdrive as well as a lockup mechanism. The 4L60-E is the "E"lectronically shift controlled version of the 4L60.

After putting the servo in, everything now in the tranny is new. C6 transmission slow to engage in work. A fellow racer said that was possibly due to trapped air inside the valve body, I found that if I rapidly bumped the transbrake button a few times before lighing the 2nd stage bulb, the problem disappeared. Mine also takes longer to engage than any other auto I have ever had. It sound to me as if the pump might be going out. Once it warms up, the seal expands enough to work properly. Also, when the transbrake was applied on the starting line, the car tended to roll foreward a few inches. If you get one of the old HD forward drums, be sure and get a 30-30 input shaft with it.
The second problem is a loss of line pressure over time due to the large quantity of crossleaks found in the oil pump as well as the valve body. Cleveland / Big Block Pattern – 7-3/4" between top two bolt holes. It's common in extreme temperatures for a delay to occur in the transmission, especially in frigid temperatures. Joined: Thu Feb 23, 2006 5:32 am. Here's what you need to know about delayed engagement and what to do if it happens to your car. C6 transmission thump into 1st gear.
