1992 Camry transmission clunk when deaccelerating/accelerating

[Techventure]

I had the front engine mount replaced on my V6 - 3VZ and most of the what I call a clunk has been solved but when travelling at most speeds and taking my foot off the accelerater the transmission seems to clunk and when I reapply acceleration it clunks again. Its like the transmission has to catch up or decrease to the engine speed......my way of describing it!

The mechanic who replaced my front engine mount talked to his friend in the transmission business and they feel it may be a chain in the transmission that is stretched (like a bicycle chain) and the slack causes the clunk. I have never heard of a transmission using a chain, however, I have no clue. Is there a chain? If there is, can it be tightened? If there is not, is there something else that can be tightened? What can I do to eliminate the clunk?
The fluid was changed last year and is red.

We are retired and can't afford a transmission rebuild. Everything else is in good shape on this 1992 with 229,000 kms. at this time.

Any help, as has been provided in the past from you folks and greatly appreciated, would be very much welcomed.

Thanks.

I am sure that your trans has a seperate oil reservoir for the trans axle and it takes gear oil and the trans takes trans fluid . the noise your describing is what they sound lie when they have lost the oil in the transaxle right before it goes out. you should check the tran oil levels make sure that gear oil is present.

Thank you for your input.
I am not aware of a seperate oil reservoir for the transaxle that takes gear oil!

I have lookd in my car manuals and can find no mention of having this. I have been driving this car for a little over 15 years and have never come across what you are stating.
Could you tell me where you got your information from? I have a V6 3VZ engine in a 1992 camry. Could you send me the information you are using?

Has anyone else reading this be able to comment on this gear oil claim?
Thanks.

Hello Matthew24u.

I took a further look at my Haynes manual and you are correct, there is a differential filler plug. It takes the same fluid as the transaxle, Dextron II or III. I will check the level to see if this eliminates the clunk as I have described.
Thanks.

The differential was checked and found to be full.

Does anyone have any idea what causes this hesitation/clunk I have described?

Thanks

By the symptoms described it does sound like it could be a stretched chain, these units do take a chain, a drive and driven sprocket within the transmission to act as a power transfer unit. If it starts to show skipping besides the ´catching up´ it could be the chain.

Now the problem can also be worn out clutch discs, which would require a rebuild of the unit.

Hope it help!

Thanks Andy,

When you say clutch-plates you're referring to inside the transmission??

Yes

Sounds like a typical symptom of worn inboard CV joints. Check the boots for tears. Grease gets thrown out, lubrication is gone, they quickly wear out.

New axles and boots installed this year.
Thanks.

I changed trans-axle and differential fluid last year, on April 10, 2011.

Thanks.

Sorry, I reread your first post and deleted the question.
