It is important to keep some items in mind when you purchase a used bell housing. You should always inspect a used damper disc to ensure it will remain reliable. You also want to inspect the used aluminum bell housing in the event it could have debris, corrosion, and small scratches.

Auto Technology Repair inspects every item before it goes out, so you may notice some minor wear. This is normal, and it will not compromise the overall integrity of your component.

Damper Disc

Any damper disc you get from Auto Technology Repair will be used. Auto Technology Repair is unable to supply new damper discs at this time by themselves. However, you have the company’s guarantee that each disc receives careful inspection before going out. Although they may have minor wear and tear, they will still work optimally.

Greater Risk With GT-R R35

Due to its design, the R35 Nissan GT-R has a unique risk for bellhousing failure. From the first GT-Rs in 2008, the bellhousing has always been a weak point due to the separation of engine and transmission. The bell housing is mounted on the back of the engine where it has needed to adapt to a rearward-facing driveshaft going toward the transmission. Nissan was not able to come up with a better design where the transmission was more firmly in place. As a result, there is a chronic push and pull effect between the transmission and engine any time you accelerate or decelerate.  In three design attempts, Nissan has not been able to produce a reliable bellhousing.  This is why we at ATR have taken it upon ourselves to eliminate the CAUSE of failure.  Our modified flange gives the rear driveshaft ample room to float between engine and transmission without abusing the bellhousing.  Our upgraded bearings are also better suited to handle constant abuse.

Signs of Damaged Bell Housing

A failed, or broken bellhousing will exhibit a rattling noise at idle, while stopped at a red light, and at low speeds.  The rattle is caused by the shaft moving around inside a damaged housing or a bearing failure.  Our upgraded V2 housings will eliminate future failures

Warranty

As with any component, it is important to remember that accidents can and will happen. Every V2 Bellhousing from ATR comes with a 5 year warranty, up to 1,600 horsepower.  If you are running more than 1,600 horsepower, the damper disc can and will fail – Please look into our V3 housing with ETS billet shaft and disc.  Please note that ATR will not pay installation labor in any situation, we will be limited to the replacement value of the bellhousing.  We will cover shipping to and from our facility for the first year only.  A damaged housing must be returned for inspection before new housing is shipped.  Alternately, you can purchase another housing and we will refund once we have received a failed housing back.  In the event of a failure, we will replace the bearings on your existing housing – we have never had a housing failure, aside from a defective or failed bearing.

In over three years of manufacturing and selling this product, we have helped many clients to diagnose continuing drive train noise.  If you suspect a failed housing, please check all exhaust (including down pipe brackets above bellhousing), make sure all bolts are properly torqued on bellhousing, disc, driveshafts, and exhaust before starting a claim.  In some situations you may notice a rattle when the engine engages from a stop.  This is usually a result of a software tune that requires adjustment, and not a bellhousing issue (call or email us for more information on this).

• We will warranty ONE bellhousing failure.  If the bellhousing fails a second time, we may opt to issue a full refund upon return, inspection, and confirmation of failure at our discretion
• Our warranty does not cover labor costs, unless you have the bellhousing installed at our Gilbert, AZ facility – Highline Car Care
• Our liability is limited to the purchase price of ATR bellhousing plus shipping
• We will replace failed bearings on your V2 housing for 5 years from date of PURCHASE, for the original owner in the original vehicle only
