Is there an overhaul kit for the Allante tranny?

RickyRidesABike · #1 (**permalink**) 02-21-07, 12:00 AM

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.

Not that im aware of, but it may depend on year.

As for the turbo(s) which engine, and how much boost you planning to run?

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.

pick up a Hot Rod Magazine ....

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 there's an overhaul kit for the 4T60 tranny. NAPA has it, but it's not for the faint of heart. This tranny's quite complex...

Yes there is....

Best place (and cheapest) to buy parts is:
http://www.bulkpart.com/

or

I also recommend that you buy a rebuild video. It makes it sooo much easier. Here's a link.

so now that i kno there's a way to rebuild the tranny, is there anyway to beef it up to handle the extra power?

RickyRidesABike · #9 (**permalink**) 03-18-07, 03:03 PM

i was just wondering if there isnt a way to beef up the tranny could i just swap in a GETRAG 282?

Kcryan · #10 (**permalink**) 03-18-07, 03:12 PM

The 282 was a 5 speed was it not?

If so you just opened the below pictured can....But i like the idea.

RickyRidesABike · #11 (**permalink**) 03-18-07, 05:10 PM

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.

Opened a can of worms was what i was hoping to get across...guess i failed...

Either way, if you do do it, please please please document it well as a 5speed allante would be a dream

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.
