I recently purchased a 1990 Honda Accord and after a few weeks noticed some slippage when in stop and go traffic. I went to a local Transmission shop and after an inspection was told how lucky I was as everything was burnt. Since this was to be used by the spouse and daughter, I paid to have it rebuilt.

Once I got the car back, I've come across the following issue which has me and the shop stumped.

I depress the brake and shift from park to D4, I feel the transmission positively engage. As I let off the brake and start moving forward, there is a second engagement which is abrupt. This second engagement feels more like dropping the transmission from Neutral into Drive.

As you can imagine, I took the vehicle back and I'm told they rebuilt it again. After the second time and the problem did not go away and the slippage had returned at slow speeds, they found me knocking at their door again.

After two weeks and being told they put my transmission in a second car and it work perfectly, I was told the problem can not be in the transmission.

I contacted the person who sold me the car and he then disclosed the transmssion had been swapped prior to him purchasing the vehicle. He never experienced the double engagement but did say he had the slippage at slow speeds.

I'm now starting to wonder if I have a TCU on the brink of failure or is it mismatched?

The current Transmisison is a MP1A which was not in the vehicle when new. The TCU is 28100-PX4-932 (3LZ) and had a big black "X" on one side. Previous owner had now knowledge of the black "X" or it's significance.

TCU is not shooting any errors.

Any help would be much appreciated.

Thanks

tofast4uh22 - Went with an AutoTranny for the daughter as she does not know how to use a stick. The last two times I tried to teach her was painful, for me my wallet and the car.... Clutch had been rebuilt less than a year prior but required a changeout after our "LESSONS"...

Mista Bone - Any tricks or is it adjust and drive to see results?

Thanks for the suggestions..

the cable from the tb to the trans "might" help during shifts under significant throttle, but just lightly crusing it wont matter much.

id ask the tranny shop to borrow the tcu from the car they tested the tranny in.

are you sure they did that... thats alot of work to test a tranny... id put a different tranny in your car before i tested yours in another car.

I'm thinking the shop is giving him the run around......

Proper cable adjustment means everything. The 91 EX Civic I've been driving, I took it back to the former owner. He mentioned the tranny would get slushy, not hold second gear correctly, as well as other items when it got hot.

I let him drive it again after I adjusted it and drove it 7,000 miles. Totally different animal and he wanted to buy it back right there.

the older accords that cable was there to increase line pressure as you applied more throttle. I have never messed w/the d trannys so idk of they work the same way or not.

Mista Bone

Yep, they work the same.
