4.0 Torque converter With 2.8 Or 2.9 a4ld Trans ?

[BrucesBlack]

Was Wondering If anybody Has used a 4.0 Torque Converter with a 88 2.9 Bronco II a4ld trans ?

I'm Asking because I bought a 89 2.9 B II Trans and the Stall Speed of the Torque converters are Different , And to add to that , I cannot Control Tcc Lockup , Therefore NO Overdrive , Which Is Fine As I do Mostly City Driving , But With 33" Tires And 3.73 Gearing The Stall Speed Sucks , Takes off very slow and Sluggish ,

Just wondering if anybody has used the 4.0 TC with the 2.8 or 2.9 a4ld trans ?


If so I was wondering if you took note of the Different stall speed and Rpm change between the two ,

Thank you in Advance !

Well I guess not , Guess I can Run the BII a4ld until It dies .

I ran a 2.9l A4LD behind my 4.0l for a while. I would go with the 4.0l converter over the 2.9l. The stall speed was just too high, I really had to beat on it too get it to move like it did before.

Yes I noticed that and Do not Like it At All . I Don't have the time to do the swap right now and with Working in the Weather its not that fun this time of year . I plan to Put the Proper 93-94 A4ld So I will Have Overdrive , But Well see How long that takes me haha .

TCC lockup and OD are not the same. Loss of TCC lockup should not take out overdrive gear.

Well Od Does not work at all in this trans then , Either way I will not have OD with this trans in my Vehicle .

Sounds like electrical issues to me. The two things controlled by solenoids dont' work, tells me there is a power issue.

I've tried to Wire in the solenoid and that did not work . I have other threads on my BII trans in my 91 Ex Sport or Navajo .
