TCC Solenoid Circuit DTC – Buick Rendezvous 4T65E
Problem – Diagnostic trouble codes (P0742, P2761, P2764) relating to the torque convertor clutch, may be caused by an incorrectly routed internal wiring harness that can short itself out over time.
Solution – To solve this problem, reposition the tan colored TCC solenoid so that it does not come in contact with the metal wiring harness retaining clip.
TSB 06-07-30-023 – 4T65E transmission 1-2 Shift Shudder
Problem – Shuddering or shaking may be felt during the 1-2 shift, under light acceleration at speeds below 25 mph.
Solution – To correct this common 4T65E transmission problem, the entire second clutch assembly will need to be replaced.
TSB 08-07-30-016 – Slipping, refusal to shift, overheating
Problem – Slipping between the gears, overheating, refusal to shift out of a gear, and/or DTC P0894 or P0218, may be because by friction material debonding from the torque convertor clutch (TCC).
Solution – If the friction material has circulated throughout the transmission, the entire transmission may need to be replaced. It is possible to remove the material from the internal components (like transmission cooler lines and the valve body), but it depends on the extent of the damage.

Can I drive with a transmission problem?
The simple answer is yes. You might actually be able to continue driving, however there is a catch. Those Buick Rendezvous transmission problems can multiply themselves very quickly if you continue driving. So do yourself, and your wallet a favor by having your 4T65E transmission inspected by a mechanic as soon as possible.
How often does a Buick Rendezvous transmission need to be replaced?
Maintenance and responsible driving habits can greatly extend the lifespan of a transmission. However, we’ve noticed the typical Buick Rendezvous 4T65E usually lasts between 130,000-180,000 miles. A good quality remanufactured transmission on the other hand, can last a lot longer than that with proper maintenance.
How are Buick Rendezvous transmission issues diagnosed?
To accurately diagnose most Buick Rendezvous transmission problems, a mechanic will need to connect an OBDII code reader to pull the diagnostic trouble codes. Then they will need to perform a visual inspection to verify their diagnosis.
How is a Buick Rendezvous transmission replaced?
Because there’s ‘a lot engine’ in a relatively tiny engine bay, the motor may have to be unbolted in order to gain access to the gearbox. After installing that new Rendezvous 4T65E transmission, ECU will have to be reprogrammed / reflashed to accept the new transmission using the latest GM subscription.

How to Solve Buick Rendezvous Transmission Problems
Solution A: Buy a Used Buick Rendezvous Transmission
Buying a used 4T65E transmission might seem like the most affordable way to solve your Buick Rendezvous transmission problems. However, you don’t really have any way to know the true condition of the internal components. And the 30-90 day warranty that most junkyards give you, might not cover labor charges if the first used 4T65 one doesn’t work right.
Solution B: Buy a Rebuilt Buick Rendezvous Transmission
Buying a rebuilt 4T65 transmission might seem like the next best option, but there are some things to consider here too. First of all, most mechanics use what’s called a master rebuild kit, which takes the transmission back to its stock form. This won’t correct any of the factory design flaws, which can reduce the transmission’s service life. And secondly, the rebuilt transmission warranty may only be honored by a small number of shops, in a specific region.
Solution C: Buy a Remanufactured Buick Rendezvous Transmission
To get the most life out of your stylish little CUV, you may want to consider buying a remanufactured Buick Rendezvous transmission. They’re often upgraded or modified to correct for OE design flaws. And the warranty on a remanufactured 4T65 transmission will usually be much, much better.
