Measure specs and make it right. As you can imagine, everything in a valve body mod is a coordinated system. You may have to before you can post: click the register link above to proceed. I never really even took it into consideration until it was already bouncing on the limiter, only then did I modify it. Can anyone speak of other shift kits? What happens if I soften B0 and when c1 and B2 don't have the same timing when going into 5th gear.

A650E Performance Transmission

The effects of this are shifts that are not overly uncomfortable at lower throttle openings, while at heavier throttle, firm shifts with much shorter clutch application time and increased clamping force can be achieved. The clamping force that is required to apply the clutches and bands is increased by 30 to 40% at full throttle. Transmission and valve body upgrades are not only for American made vehicles anymore. Our state of the art package of modifications produce the strongest and most reliable gearbox available anywhere. This includes models from Toyota 1992 and older Supra , Lexus Early model Soarers , Jeep and Volvo. The framework is present for an extremely strong transmission that is to be used in a high performance or extreme duty application. I'm suprised you'd share the info.

If you don't mind, a question. I've never split a valve body into its two halve but it really doesn't seem like a big deal to me. Nothing, just don't apply power to them and all is well. We carry kits for dozens of different automatic trans. We carry kits for dozens of different automatic transmissions—shop now! The case was face-up on my bench so I held them in place with the studs and afterward rotated the pic in Photoshop. These automatic transmission rebuild kits will take the guesswork out of your auto transmission repair or rebuild by supplying all the small pieces and parts in one convenient kit. As well as spare valve body.

. With that being said, if anyone wants the repair manual on the transmission or the Toyota automatic transmissions training course, I'd be happy to email it to one person. Ideally, I'd like to not share in public the rod lengths from various kit builders. For additional information, see the Global Shipping Program This amount includes applicable customs duties, taxes, brokerage and other fees. Various Toyota models tweak these adjustments as seen below: Accumulator pistons with limiting rods are shown here: note the C0 Accumulator has a rod in this shift kit, it's the only one I've seen with it.

When adjusting the valves that Toyota designed into the transmissions, what does the primary and accumulator control valves do specifically with the 'shifting'. Also should mention the dragon tc with 2800rpm stall, multiple fluid coolers and a disabled no 4 solenoid. Is there any reason I can't use dex instead of t4? I need to see where 5th hits on my car, but I suspect I'm well into the triple digits by then. I would also think good things would come from changing out the springs for the shift valves. All hydraulic functions of the transmission are based on this pressure- what is especially of concern for these purposes is the clamping force which is applied to the clutches and bands to get them to hold against engine torque. However, to modify it requires a whole other side of the brain. Yea, sorry, I should have provided a bit of background.

Flow through the cooler and lube circuit is increased and the converter clutch application time is also reduced. It's just bad form and they help us out from time to time. As well as controlling shift timing and shift quality, it is also responsible for directing hydraulic pressure to the cooler and the lubrication circuit. I suspect it's not necessary unless you're really trying to boost in 5th gear. The end result is a transmission that provides you with worry free operation under the additional stress that is associated with any high performance application. So this is why I'm interested in what you're doing with the A650. It goes over the A750 box, but Auto Transmissions are all similar in design.

It was quite an undertaking. A stainless rod would wear the valve body and accumulator piston. The idea is to raise this pressure only slightly at light throttle but increase it by 30-40% at full throttle- where it is really needed. If anyone wants info on what's involved with properly modifying the valve body, I can post some from an article that I wrote on the subject a while back. . In particular, how would you retard the timing and close the throttle upon shifts? First things first, the 'shift kits' I've seen out there are pretty simple in design.

That said, here is the article. These automatic transmission rebuild kits will take the guesswork out of your auto transmission repair or rebuild by supplying all the small pieces and parts in one convenient kit. These are hydraulic circuits that are parallel to the components that are used for shifting. Normal driving they simply shift like you would expect but the harder you push the vehicle the more responsive the shifts become. I was bouncing off the rev limiter very badly with my original trans which I did the above modifications to after boosting on it for a year daily driving and 80+ track runs. These calibration inadequacies quickly manifest themselves as extremely poor shift quality, and more often than not, severe damage to the gearbox is soon to follow.

Again, it all comes down to knowledge…. If I were to try taking that tranny apart like you did I guarantee it would never operate the same again after I put it back together. At the risk of oversimplification, there are a few things that are done in concert to create much more favorable operation of the gearbox. I assume that adjusting line pressure dial that's accessed when oil pan is removed will help a bit, but I wonder if the kit would make any further improvement I do highly wish to fit it before Aug 17th. This good proof of the difference the simple mods can make. Toyota switched from Steel balls in the valve bodies to plastic ones for this reason.
