    I had a th200 in my 79 monte…its crapped out. I swapped it with a th350.. just saying the th200 isn’t a good trans.

    Yeah, I agree the 200 and 200C had a bad reputation that was in part at least deserved on the factory units. However, with mods like metal replacing plastic internals, HD clutch discs, improved pump, modified shifting, and other internal improvements It has proven to be an effective and dependable trans in a class of drag racing and hot rods due to it’s small size, light weight, and low HP use.

    One of the reasons Im choice’d with a 200CR or a late model 700 is because the bell-housing adaptor offered by D&D Fabricators up in Michigan can only accommodate these 2 tranny’s. I hesitated with the 700 because of its size,; Im trying to limit the amount of sheet metal/tunnel removal and fabrication and felt the engine is under torqued to benefit with a 700. I thought going smaller is best and Im not planning on racing…..just cruising along Route 66 in the summertime! That being said what are your thoughts on a 1990 or later 700 tranny

    First, I am not an expert trans guy. I just do my research, talk to the experts, and go with what looks like the best option.
    When you mention the 200CR is that a typo? I think you mean a 2004R and I’ll go with that here.
    Later 700R4 I believe is known at the 4L60 which, based on what I know and see is a great trans and still has the mechanical linkage vs the 4L60E which works with a ECM. I guess the case is a little smaller on the later 4L60, I think this is the one I have heard people call the “baby” 700R4 but I am not positive. I believe the 2004R is smaller than that one but not also not positive. In either case I believe you will have significantly more tunnel mods than a 200C and will need to add a new linkage and driveshaft mods, although you do get OD. I prefer the 2004R 2.74/1.57/1.0/OD vs. the 700R4. 3.06/1.62/1.0/OD with it’s tighter ratios. The 2004R can be built very strong, I think it’s lighter than the 700, and uses less HP. Although not as strong as the 700/4L60, it is plenty strong for our apps. Check out the after market trans sites for more info-Monster, Bowtie Overdrives, TCI. We chose to go with the small 200C 3 spd trans for reasons explained previously.
