Hi guys,

I own a 2002 TJ Magna Sports.

On monday I sent my car to a transmission specialist to get a problem checked and it still has not been rectified. This problem only happens when i shift to reverse. When I make this gear shift, the car makes a big thump and then it is capable of rolling in reverse but if i hit the accelerator, the engine revs, but does not pick up speed.

The specialist said "It sounds like you may have an issue with your reverse clutch cushion spring. The failure of these springs is very common on the F455 transmission." Apparently (or so it seems) this is the case and he found the spring to be in four pieces. He replaced the spring and quoted me a whopping $1200 dollars!!! Problem is that despite this, he still notices the car does that large thump which he thinks is the reason to the damaged spring. He assured me that he will get to the bottom of this free of charge. However, he has checked several times and still cant fix the problem. He told me he even contacted the Australian Transmission Rebuilding Association to get answers and he couldn't find any. Now he tells me that if he cant fix it, he'll have to just give it to me, still with the price of $1200.

What should I do?

I say its a wave spring issue. Get it flushed and if you find little metallic bits, the wave spring has gone kaput.

Sounds more like coolant has leaked onto ecu and is in limp mode. The number of auto shops whe have rebuilt transmissions for no reason is shocking

Get him to check the ecu

Check the fuse for ya reverse lights in the drivers footwell. Mine did the same thing when I popped the fuse. Exactly the same actually.

The fuse is a light symbol with a R in it. Think it's a 10a from memory

Engine flush and ticking noise help

OP if your mechanic does not know – maybe you need to circumventing him and going direct to…
Australian Transmission Rebuilding Association

Checked the fuse, seems to be intact. The car now can go in reverse but still has a nasty thump when in reverse. The specialist checked the ECU and it waiting for expert opinion.
