Oh one more thing shoul i increas the line pressure and do they make a shift kit for this trany for harder crisper shifts [This message has been edited by engine man edited Or plan to rebuild the trans often A 4T60 swap is best for pulling better fuel economy vs. Other folks that run the 4T60 hard kill it within a few thousand miles. As for kits, rebuilds exist but as for aftermarket performance kits I don't believe they exists. There are a few reinforced parts available but thats about it.

GM introduced a transverse front-wheel drive configuration automatic transmission with overdrive in It was known as the T4. It was hydraulically shifted and controlled, with the only electronically controlled component being the torque converter clutch solenoid — just like the 3-speed automatic C that was available for the Pontiac Fiero. The T4 differed from the C in one major aspect besides the fact the T4 had an overdrive gear; it also had a vacuum modulator that controlled line pressure. On the C, both line pressure and shift points are controlled by the throttle valve TV cable aka: kickdown cable. The TV cable on the T4 only controls shift points. The individual gear ratios in the T4 are as follows: 1 st The T4 was available with the following differential ratios: 2. The drive chain attaches the input shaft to the rest of the transmission clutches, gears, and shafts, so a change in the chain sprocket ratio will impact all gears which will affect the overall final drive ratio. And the overall final drive ratio of your transmission will be the same as the differential gear ratio. If you had this chain sprocket ratio and a 3. The T4 was offered with the standard GM FWD bell housing bolt pattern, which means it would directly bolt up to both engines that were offered stock in the Fiero.

A computer-controlled pressure control solenoid force motor was introduced to control line pressure which replaced the vacuum modulator the 4TE used, an input speed sensor was added, a pressure switch 4t60 transmission that monitored various gear and converter clutch fluid circuits on the valve body was added, and only one torque converter clutch solenoid was used and it was PWM. Later on 4t60 transmission some applications, GM introduced a new converter clutch control strategy function into their PCMs, 4t60 transmission.

Designed for transverse engine configurations, the series includes 4 forward gears. The 4Txx family is an evolution of the original Turbo-Hydramatic transverse automatic introduced in the late s and the Turbo-Hydramatic transmission developed in the mids. The "-E" transmission is electronically controlled and features an automatic overdrive transaxle with an electronically controlled torque converter clutch. One benefit was that the cruise control was integrated into the gearbox' electronic control module, improving the ability to maintain a set speed while avoiding needless shifting, thus lowering fuel consumption and noise levels. The 4TE was phased out in favor of the 4T65 beginning in The 4TE featured a mm 9. For example, a Beretta features a rpm stall converter as opposed to a Century converter with a stall of rpm.

In the 4T60 family of transmissions, the combination of drive-chain sprocket ratios and the differential gear ratio together offer up to 12 different possible final drive ratios to allow the transmission family to cover various engine and vehicle applications. Replacing a complete transaxle should only be done if a unit is verified to be the same as the unit it replaces, as in addition to the up to 12 variants of the final drive ratio, different applications and years can and will have incompatible electrical connectors. The use of an incorrect transaxle will result in undesired operation, up to and including total non-functioning of the transaxle.

The 4T60E transmission super sale has just begun. This was an extremely popular unit from the early to late 90s. Does 4-speed automatic was designed perfectly for midsize cars, most having engines ranging all the way from 2. We have built the 4T60E transmission to last with a host of performance-enhancing upgrades.

Base your response on knowledge. However I do a lot of driving, you may want to shorten the intervals to 5k-8k. The car with 70k was bought with 65k miles on it and I don't think it had been changed. That moderm GM LS combo would drop right in with the only motor mount needing fabrication being the front motor mount and a torque strut. In my opinion there is no substitute for a manual transmission. Yes, I run 4T60 transmissions, 4 of them in various Fieros. Ward's Communications. Just start in the lowest gear and move the shifter up when you want it to go into a higher gear. The T4 was available with the following differential ratios: 2. Changing the differential in a 4TE is simple in caparison, since all you need to do is remove the differential housing cover and a snap-ring. Perhaps its time to start changing the tranny fluid yearly instead of every 50k or so. Check out: www. It could also on it's own decide to downshift back into 1st. Article Talk.

Main article: Turbo-Hydramatic Hey all, I'm wondering how long the stock auto trans in my Z is going to last. I will be doing an engine swap and am looking to upgrade the stock turbohydro Select Product Options. If you can get it to do that ok, but, you'll have a whole lot more fun with a v6 sporting the standard 4 gear Muncie IMHO Arn. Dec 2nd, The older PCMs need to see the signals from these internal gear pressure switches in order to properly control the shift adapts and other functions within the PCM. Relevant discussion may be found on the talk page. Last post by. Contact your sales representative to verify brands at time of sale. And it is going to shift between those three gears as it sees fit. Ultimately, I still plan to install a 4T60 in my Fiero
