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.
