The transmission is done . Sam feels confidant it will hold the HP we will be capable of putting
down. It’s nice to give a shop time for a project, but I’m sure the next one will be quicker if
anyone is interested. So here is the update, Torque converter modified to fit the projected HP
and performance curve of the motor. Sam worked with ARD on this so it is truly matched to the
motor and turbo.All the transmission bands were replaced with Kevlar as well as Kevlar
clutches. Sam reprogrammed the Valve body custom configuration of the new solenoids, for
smooth shift as opposed to the normal hard shifting tire chirping kits. Sam and I talked back in
May on just how bad a lot of shift kits are . The load of those shift will kill the transmission in no
time. Sam believes in smooth sycro shifts. For those who want this modification will need to
think hard on the expenditure, and want to stay with the GT. A manual swap is almost half the
price
I found out the Torque convert was Furnace Brazed with a Stall I think of 2400
Furnace brazed fins: The fins inside a stock torque converter are usually held in place by
bending over a tab on the end of the fin. This is fine for a stock application, but under the stress
a race converter is subject to, the fins will come loose. To stop this from happening the fins are
furnace brazed where they are bent over, basically eliminating the fins from loosening.

Furnace Brazed Turbine
Furnace brazing strengthens the turbine assembly for the added torque it is required to handle.
It also increases the overall efficiency of the torque converter.

Transmissions starting with a serial number of 06J and later have the latest valve body revision
and supposedly no issues with them? M
HexMod suggestion
Trans temp: keep it at/under 180*F, limit spikes to 200*F
I had my valve body replaced by with a ReamMan.com valve body. It’s only been two weeks but
no more hard 3-2 shifts and no more slippage. My transmission guy inspected the it before
installing and said it even looked like better quality than the OEM component. Right down to the
solenoids.

I wish we had access to the TCM as it is important to adjust the transmission parameters to help
it deal with the added engine torque. The shift speed and possibly the line pressure can be
changed via the ECM thru HP Tuners SW, but it also controls spark timing and I haven’t been
able to smooth it out, so I’ve still got it set to stock.

4T65EV/GT Volvo model – $1899.95
Volvo used this model transmission in a few select models including the S80 and the XC90
during the model years of 1999-2005. This version of the 4T65E is NOT compatible with any
GM vehicle as visable in the above pictures and has a number of differences. Due to the low
production numbers of these transmissions compared to the GM version the core availability is
very limited and because of this we require you to send us your existing transmission to rebuild.
There is a great deal of attention and time that goes into each and every rebuild and there are
also a few common failure areas, especially in the 99-02 models, and these are addressed and
upgraded during the rebuild. Below is a list of items that are replaced and are included as an
upgrade in every 4T65EV/GT Volvo version rebuild. For High Performance applications for
upgraded T6 models please look at our 4T65E High Performance rebuild for details.
-Thorough inspection during dissassembly
-Any questionable or excessively worn hardpart is replaced
-Hardened 4th clutch shaft
-Seals, gaskets, orings, and teflon sealing rings
-New USA made filter
-All new Borg Warner clutch plates and modified clutch stackup for improved shift feel
-New Forward apply band
-New thrust washers
-Common failure bushings replaced, others inspected and replaced as needed
-New stator support bearing
-Select bearings replaced standard, others inspected and replaced as needed
-New aftermarket input sun gear
-Reconditioned input clutch piston
-New Morse HyVo HV-093 Gemini chain set
-All new solenoids in valve body including
-Borg Warner PCS for 97-02, OE Volvo/Bosch for 03+ model years
-Borg Warner TCC PWM solenoid
-OE AC Delco shift solenoids
-Pressure switch manifold cleaned and tested, replaced as needed
-Wiring harness thoroughly tested and replaced as needed
-Transgo shift kit- this is NOT a performance kit but greatly improves shift feel,
includes a few upgraded internal seals and vastly improved accumulator spring set
-Sonnax Sure-Cure kit which includes these upgraded parts
-TCC apply valve
-TCC regulated apply valve
-TCC relief valve
-Improved boost valve and sleeve
-AFL valve and sleeve
-Lube tube retainer, improved check balls, pump slide pivot pin
-Precision reman torque converter matched to your vehicle
-18 Month / 24K mile warranty*

Thanks for your email Ron.
In just quickly looking at the Level 10 option vs. our own, there are some pretty significant
differences.
First, the kit we sell includes everything in the Level 10 kit, but it also includes the 3rd gear
band which you will need for the rebuild. Our kit also includes two filters. It has 2 because
there were 2 different ones used in that transmission and you won’t know which one you have or
need until you get it apart. I can’t say what else is potentially missing from that kit, but just
looking at the photograph is does look like a lot less parts. It could be that their gasket set is not
the full gasket set we sell. It looks like it does not contain any of the parts to rebuild the valve
body but I could be mistaken.
As far as holding more hp than a stock kit, I would say our kit is going to be better than stock
but it is not a high performance kit. For this transmission, high performance parts really have
not been made available or manufactured.
The best way to improve upon the durability and power of the kit is by adding a shift kit. The
one I would recommend is part number TRG-SKTF80SC for $139.38.
Let me know if you have any other questions or if I can help in another way.
Thanks,
Brian

AW NOTES
There are also modifications that can be done to the PCM to firm up shifts. When I had my PCM
flashed they turned torque management off and turned stall torque off. This resulted in firmer
shifts and a more connected feel. I am not 100% what these features do, but since its in the
PCM (not TCM) I would think that TCM sends a signal to the PCM to reduce engine output
during shifts.
One of the clutch pistons is thinner in the Supra A340e due to a slightly shorter bellhousing and
different TC. Some of the kits that upgrade the Supra trans include a billet piston. I’ll upload a
pic later. The Lexus version (and our Jeeps) have a thicker piston and don’t require the billet
version until you are trying to go over 700+, which I wonder if the 4.0L is even capable of
holding that anyway.
I found this article on Supraforums.com on how to make your A340/AW4 last. It talks sbout how
you can shim the accumulators. Which will allow quicker shifts, and by doing so, reduce the
amount of time the clutch packs slip and therefore creating less heat. Not super necesary for the
slow rock crawling type, but this can be useful for the street jeepers and jeepspeed go-fast
junkies.

It’s not so much about how much power it can take, but rather what kind of driving it can take. If
you drive the car carefully, the stock sprag can handle 600hp. But driving carefully is making
sure to shift under 6000rpm, and letting off the gas between shifts(never doing any full boost
shifts). I’m hoping these sprags will survive at close to 8k rpm and full boost shifts without
snapping into pieces. My car makes close to 700whp when I’m at 32psi. I will be testing soon
