overhaul kit for the Allante tranny? 4T60 or 4T60E rebuild kits
I was just wondering if someone made one and how much it cost. I was wondering because im planning on suping up the engine and putting a turbo or possibly dual turbos on my allante and i hear that the trannys give out after so much horse power. Any help would be great appriciated. Thanks.
Yes, there is a rebuild kit available. I rebuilt mine myself. Use a 4T60 or 4T60E rebuild kit depending on what year of Allante you have. You will have to buy a valve body gasket that is specific for the Allante. There is also an extra 4th gear clutch disk on the Allante F7 transmission but mine were good so I reused it. It cost me about $80 for the rebuild kit. I believe that there are aftermarket hardened parts available for this transmission to make them tougher.
Adding a turbo would be very neat but it'll be a challenge. The hardest part will be getting the fueling correct. Does your car have a 4.1L? You might consider swapping in a 4.9L and using the heads and intake from your 4.1L. You would then use and adjustable fuel regulator to handle the extra fuel requirements. This setup would be good for about 225hp. Good Luck!!
if you dont live in a area where you MUST SMOG the car,
things get a whole lot easier for the turbos and the trani mods.
if you got access to a chip burner, and you know how to
program it, it gets even easier.
but, anything and everything can, given enough cash,
modified and hot rod'd. whether a pre-made-kit or
your-own-kit, the results can be ... whatever you want.
I have an 89' with a 4.5 however i belive that it is high output because the car scheck thing i did ( it's like carfax only diffrent) had HO after 4.5 liters. And as for boost im not planning to run too much. maybe 7-8 pounds.
Yes... I installed a Transgo shift correction package to beef up this transmission. You can also buy hardened parts and have a custom torque converter made to handle the extra power.
which model number is the best for my car, and stringest. also about what do you think a custom roque converter would cost? Also this is kind of off topic but i sit possible to lower an Allante? I was just thinking wether or not the dampening system would still work or not.
I had a torque converter shop take my original torque converter and beef it up for about $200. They weld a plate across all the fins and suage the fins to the case to make it a lot stronger. It also raises the stall speed which helps acceleration.
The Allante is not an easy car to lower but it can be lowered about 1-1/2 inches. I'll have to dig up the procedure on how to do it if you're seriously interested.
thanks for the info about the torque converter, do you think it would cost about the same for me to have it done, and can a repair shop do it or do i have to take it to a performance shop. Also even though im probably not going to lower my car until late spring because I took a couple months off of work to play lacrosse, I'll be broke. However I'm still very intrested in seeing the procedures to lower the car. A few questions regarding the drop, I am going to have to buy anything or have anything custom fabricated? about how much will it cost? will the speed dependent dampening still work? and will the ride be stiffer or softer? Thanks for the help and information you've provided me with so far, I'm very happy that there's somewhere I can goto to get information and help with such a unique car.
With regards to torque converter upgrading, you need a shop that specializes in torque converters and has the equipment to open one up. A very few transmission rebuild shops have this capability.
so when I lower my car how stiff is the ride going to be? Is it going to be like the highway stiffness, just cruzing around? Also what kind of springs would I use for the front.
